[00:02] <amr00t> hello guys, my vps keeps rebooting when running a python script with 50 threads (12gb ram and 6 core) please how do I find the exact crash reason from this syslog http://termbin.com/lohvr
[00:08] <fluiD> I'm SSH'ing into my ubuntu server and my arrow keys don't work. How do I go about debugging this?
[00:09] <fluiD> such as if I pull up a man page, I can use enter or space to go down, but the arrow keys don't work.
[00:09] <fluiD> the up arrow works for bash history
[00:10] <leftyfb> amr00t: contact your VPS provider
[00:10] <leftyfb> fluiD: what OS is your client running on and what ssh client are you using?
[00:11] <fluiD> leftyfb, I'm using WSL on Windows 10 with OpenSSH
[00:11] <MrPockets> well I feel dense.  Trying to make a bootable USB drive from an ISO.  Startup Disk Creator lets me browse and select my ISO, but when I click "select" it doesn't show up in the ISO list..
[00:12] <MrPockets> and unetbootin goes through the process, and gets to the boot menu, but then when I select the image to boot to it just flashes and goes back to the boot menu..
[00:12] <leftyfb> !wsl | fluiD
[00:12] <fluiD> err, yes, sorry. Ubuntu 20.04 in WSL
[00:13] <leftyfb> fluiD: your issue is one of the WSL system, not ubuntu
[00:13] <fluiD> leftyfb, the arrow key works in bash but not in less. That's still a WSL problem?
[00:13] <leftyfb> fluiD: yes
[00:15] <fluiD> leftyfb, actually, I just fixed it. In Cmdr I had to change the command line of bash from -cur_console:p to -cur_console:p5 and now it works fine.
[00:15] <fluiD> but thank you very much for trying to help me!!!
[01:00] <kxsl> I'm trying to make some docker images based on the the official ubuntu image. i'm stuck at adding a gpg key to check the signatures for a repo i want to use. the image says gpg is not installed. how can that be? i thought gpg was used to check signatures on packages in ubuntu repos?
[01:05] <roly> hi
[01:08] <roly> hi
[01:08] <Bashing-om> !ask | roly
[01:08] <roly> Im not asking to ask a question
[01:09] <roly> Im just saying hi
[01:09] <roly> hi
[01:10] <roly> Also people have told me that I shouldnt be saying hi whenever someone enters, but I prefer to do that because it lets them now that someone is ready to talk in the chat.
[01:10] <roly> hi
[01:10] <raccoon_dog> We understand; you don't need to keep saying "hi."
[02:12] <Croran> fluiD: use pgup and pgdown or 'u' to go up in man
[02:13] <Croran> I honestly didn't even know arrows were supposed to work in man
[02:35] <Croran> alloy: can't you just put onboard in your startup items? or are you trying to use it for logging in?
[02:35] <Croran> oh he's gone.
[02:40] <Rockwood> i am unable to add ppa for install php8 on 19.10
[02:57] <Rockwood> lol
[02:57] <Rockwood> no one active tonight?
[02:57] <Rockwood> https://paste.ubuntu.com/p/FtSVrCm5pz/
[02:57] <Rockwood> i am facing this issue
[02:58] <Bashing-om> !eoan | Rockwood
[02:59] <Croran> is there a php8 package?
[02:59] <Rockwood> means?
[03:00] <Croran> means i only see php 7.4 packages available
[03:00] <Rockwood> how to upgrade now?
[03:01] <Bashing-om> Rockwood: Means - upgrade to a current release - your install no longer has support.
[03:01] <Bashing-om> !eol | Rockwood
[03:02] <Croran> i believe it's `sudo apt dist-upgrade`
[03:41] <Rockwood> actually i wanna install PHP8 in 19.10
[04:41] <starlordM> Hi, how do I check if TLS 1.2 is supported on my ubuntu OS? I'm running Ubuntu 18.04 LTS
[04:53] <starlordM> Hi, is TLS 1.2 not supported on ubuntu LTS 18.04? Please let me know. Thanks.
[05:38] <Lvl4Sword> starlordM, TLS 1.2 is supported in 18.04
[07:57] <Intelo> I forgot the name of snapshot tool that can also upload image to imgur website. Can anyone recommend?
[07:58] <ThinkT510> do you mean screenshot rather than snapshot?
[08:06] <Intelo> snapshot/screeshot
[08:07] <Intelo> same
[08:07] <ThinkT510> there's scrot for screenshots
[08:07] <ThinkT510> neofetch can also do that
[09:05] <amr00t> hello guys, my vps keeps rebooting when running a python script with 50 threads (12gb ram and 6 core) please how do I find the exact crash reason from this syslog http://termbin.com/lohvr
[09:46] <nop_> hey
[09:46] <nop_> how can i get rid of mesa in ubuntu 20.04 without it deinstalling ubuntu-desktop?
[09:46] <nop_> i want a nvidia-only setup
[09:47] <nop_> because vnccserver always seems to use mesa for everything instead of using the gpu
[09:47] <nop_> alternatively, seeing that it uses libgldispatch, how can i select an opengl backend in ubuntu?
[09:47] <nop_> i expect there to be a way to select between nvidia or mesa by default, seeing that there is a dispatcher library now?
[10:31] <TimothyP> Hi, Ubuntu 20.10 I was trying to add a DSL connection and after some fidling and a reboot now I do not have ANY network connections anymore not even after a reboot. Even if I add a new USB ethernet adapter or thether my phone I cannot detect any interface. no wifi either
[10:31] <TimothyP> is there a way to completely reset it
[10:34] <jeremy31> TimothyP: Any chance a new kernel was installed before the reboot?
[10:35] <TimothyP> oh yes
[10:35] <TimothyP> it upgrade the kernel with software updates
[10:35] <TimothyP> messed up my nvidia drivers (famous black screen)
[10:35] <TimothyP> and came back without interfaces
[10:35] <TimothyP> :)
[10:35] <jeremy31> in terminal check>  dpkg -l | grep linux-modules-extra-$(uname -r)
[10:36] <TimothyP> hang on
[10:38] <TimothyP> no packages found matching linux-modules-extra-5.8.0-44-generic
[10:40] <TimothyP> let's see if I can boot the old kernel
[10:41] <jeremy31> Use grub menu advanced options to boot into an older kernel then>  sudo apt install --reinstall linux-modules-extra-5.8.0-44-generic
[10:41] <TimothyP> ah ok
[10:41] <TimothyP> thank you!
[10:42] <TimothyP> another thing I notices is that shutting down or reboot takes ages in 20.10 , reached target "reboot" and then it just sits there for few minutes
[10:43] <TimothyP> btw those missing extra's is that a bug or did I somehow cause it
[10:44] <jeremy31> TimothyP: I don't know why it happens as it doesn't happen a lot
[10:44] <TimothyP> damn the old kernel does not boot
[10:44] <TimothyP> any way to use the installer disk to fix this?
[10:44] <TimothyP> short from wiping it, because it's my main machine :D
[10:45] <TimothyP> never mind, I got a terminal :D good to go :D
[10:49] <TimothyP> ok everything is working, thnx jeremy31!
[10:54] <lotuspsychje> TimothyP: try F1 at shutdown to see text based shutdown to see whats lagging
[10:54] <StupidDanbo> What opens the file browser when you open/saveas in an application? Is that controlled by the "desktop environment"?
[10:55] <StupidDanbo> because I was trying to find info on why the file folders can't be displayed 1st, and it's already set to do that in the normal file browser of my OS Xubuntu, but it never does it when I open/saveas in an application.
[10:56] <TimothyP> apparently it's waiting for crond
[10:59] <lotuspsychje> TimothyP: do you have some cron scripts active?
[11:01] <TimothyP> no
[11:02] <TimothyP> this is basically a clean install with some software added (vscode, mono, dotnet, godot, blender, firefox, edge, gimp, etc...)
[11:02] <TimothyP> no modifications
[11:03] <TimothyP> my desktop, laptop, all have the exact same setup
[11:03] <TimothyP> ubuntu everywhere :D
[11:03] <lotuspsychje> TimothyP: same ubuntu release too?
[11:03] <TimothyP> yep
[11:03] <TimothyP> I recently updated them to 20.10
[11:03] <TimothyP> well not update
[11:03] <TimothyP> clean install
[11:04] <TimothyP> had been upgrading for a few years, decided to make clean installs
[11:04] <lotuspsychje> TimothyP: try install stacer & preload and check your systemd-analyze blame && systemd-analyze critical-chain maybe more mysterys will show up
[11:05] <StupidDanbo> I don't know what to search for. I'm using plain English searches like [Ubuntu "what opens files in programs"] and no luck.
[11:06] <TimothyP> spooky :D but will have a look
[11:07] <TimothyP> https://www.cyberciti.biz/faq/howto-linux-get-list-of-open-files/
[11:07] <TimothyP> SutpidDanbo does this help
[11:07] <TimothyP> I searched for "linux list open files"
[11:08] <TimothyP> oh misread the question
[11:09] <TimothyP> Actually when we request an OpenFileDialog we can specify the location (that means the app controls it)
[11:09] <StupidDanbo> Apparently the thing that displays the file browser in EVERY program that can "open file", is different from the normal OS file browser.
[11:10] <TimothyP> Well there are multiple ways to get an Open File dialog
[11:10] <StupidDanbo> It's infuriating that half the time I'm dealing with files {saving}, I have to have a completely unusable interface because folders are randomly distributed in the file list.
[11:11] <StupidDanbo> I just want folders to display first.
[11:11] <TimothyP> the UI framework you are using might provide its own implementation or the app might be calling the native OS API's like OpenFileDialogEx on Windows
[11:11] <StupidDanbo> I already have folders displaying 1st in the normal OS file browser, but every program that saves files doesn't use that.
[11:11] <TimothyP> the latter requires specific implementations for each platform so usually the UI framework provides it
[11:12] <StupidDanbo> "UI framework" Is that what I'm looking for?
[11:12] <TimothyP> depends on what you are trying to do
[11:12] <StupidDanbo> I want firefox to display folders 1st when I save files.
[11:13] <TimothyP> Imagine I build an app and I present the user with an OpenFileDialog (instead of using the OS Api's) then it probably won't do what you want/expect...
[11:13] <TimothyP> but given that info... what can you do
[11:13] <StupidDanbo> I don't know. I'm not familiar with the terms so I don't know what to look for.
[11:13] <TimothyP> interesting I never stopped to think about it, going to try saving a file now in firefox
[11:13] <TimothyP> hang on
[11:13] <StupidDanbo> maybe "OS API" if not "UI framework"
[11:14] <StupidDanbo> I thought I could sort by file size, but apparently folders aren't sorted that way.
[11:14] <TimothyP> hmm in my firefox on ubuntu I see folders before files
[11:15] <TimothyP> and it's using the SaveFileDialog provided by ubuntu/gnome
[11:15] <TimothyP> not a custom one
[11:15] <TimothyP> ah and there is an option for what you want hang on
[11:16] <TimothyP> https://pasteboard.co/JQAx67j.png
[11:17] <TimothyP> when saving a file in firefox , right click anywhere then select Sort folders before files
[11:17] <TimothyP> does that help you?
[11:17] <StupidDanbo> I dunno. lemme see if I can find that. I'm in Xubuntu.
[11:18] <TimothyP> not sure, ubuntu is using the GNOME desktop environment and you are using the Xfce desktop environment
[11:18] <StupidDanbo> yeah.
[11:19] <TimothyP> https://forum.xfce.org/viewtopic.php?id=12055
[11:19] <StupidDanbo> but I already have my OS's file browser set to display folders 1st.
[11:19] <TimothyP> I searched for "Xfce file open dialog sort folders before files" to give you an idea of what I search for
[11:22] <StupidDanbo> oh damn that is hidden! I had to right-click on a file in the file browser, not right click on an image/page to save.
[11:22] <TimothyP> :D
[11:23] <StupidDanbo> OMG IT WORKS! THANK YOU!
[11:23] <StupidDanbo> I don't even know how long I've had to deal with it unsorted.
[11:23] <StupidDanbo> probably many years.
[11:24] <TimothyP> things like this can be frustrating. I mean I love GNOME for example, was finally able to switch back to Ubuntu a few years ago when Microsoft made their stuff cross platform and been using it ever since but I still cannot get over the fact that Nautilus does not support grouping files by type
[11:25] <StupidDanbo> oh, did I make the right decision in picking XFCE over Gnome?
[11:26] <TimothyP> do you like Xfce ?
[11:26] <StupidDanbo> I feel kinda weird a lot of times when I try to get info/help and most people are using Ubuntu and nothing looks the same.
[11:26] <TimothyP> if you like it, you did not make the wrong decision
[11:26] <TimothyP> Everyone has their own preference
[11:26] <StupidDanbo> I don't even know how it varies. :>
[11:26] <TimothyP> Ubuntu's GNOME makes me feel relaxed while working
[11:26] <TimothyP> whereas Windows 10 stresses me out
[11:27] <TimothyP> and MacOS makes me want to pick up my mouse and throw it out the window
[11:27] <TimothyP> KDE makes me feel like I'm in a candy store
[11:27] <TimothyP> XFCE feels a bit "dry" to me
[11:27] <lotuspsychje> keep it ontopic please guys
[11:27] <StupidDanbo> I haven't used a Windows since XP, so I'd be pretty lost. I tried to fix something on a recent Windows machine and I struggled.
[11:27] <StupidDanbo> Sorry.
[11:28] <lotuspsychje> we got a very nice #ubuntu-discuss channel you can discuss 24/7
[11:28]  * TimothyP did not know... slowly walks backward
[11:28] <TimothyP> noted
[11:29] <TimothyP> StupidDanbo let's go there if you want to discuss this more
[11:30] <StupidDanbo> ok
[11:42] <JeffJohnson> hello, I'm trying to debug with gdb a general protection fault that happens when I'm running ssmtp. The segfault happens in /lib64/ld-linux-x86-64.so.2. I installed libc6-dbg for the debug symbols but somehow gdb can not find the debug symbols for /lib64/ld-linux-x86-64.so.2. Anybody has an idea what might be missing/wrong? gdb is searching in /usr/lib/debug
[11:51] <dckusr> hmm, apt-key needs gpg-agent but it's not installed in ubuntu 18.04 docker images, is this a bug ?
[12:13] <CrazyH> Ubuntu 20.04:> XCFE4:> When I run an app ( like Firefox ) it creates a panel linked to that instance with The FF icon and some text in it ( that shows the title of the tab that the browser is currently viewing ). How can I edit the icon and the text of that launcher manually from the command line?
[12:14] <CrazyH> Also... not sure if I'm using the correct terminology, but hopefully I'm being clear enough to show what I mean :-/
[12:19] <CrazyH> in this case I want to edit the launcher panel linked to my Firefox instance so that rather than showing the title of the current browser tab, it will instead display the Firefox profile name and some other custom text.
[12:20] <CrazyH> For me this would be SUPER helpful, because I run like 6 Firefox windows at a time, all on different profiles
[12:20] <oerheks> sudo nano  /usr/share/applications/firefox.desktop
[12:20] <oerheks> ..wait, 6 different profiles :-D
[12:20] <oerheks> lolz
[12:20] <CrazyH> Yup
[12:20] <oerheks> why commandline?
[12:20] <oerheks> hmm?
[12:21] <CrazyH> Because if I can do it on the command line, I can automate it. For example, when Firefox gets launched, I can just also have it run a BASH script that does this job automatically
[12:22] <oerheks> one can change the launcher description, not the title of the webpage opened.
[12:23] <CrazyH> That's fine. The launcher description is all I care about. Maybe if I could also change the launcher icon... that would be awesome too
[12:24] <oerheks> it's all in the desktop file
[12:24] <CrazyH> But just for clarity. I'm not talking about the original launcher that launches Firefox in the first place. I'm talking about the "launcher" that appears after you run Firefox. The one that is directly linked to that instance
[12:27] <CrazyH> Well, something is odd. I have 3 instances of firefox running now, but only 1 firefox.desktop file
[12:27] <CrazyH> It looks like it is mostly language options?
[12:27] <lotuspsychje> one is snap?
[12:28] <oerheks> they all using the same desktop file.
[12:29] <oerheks> so if you start firefox with different profiles, how did you do that?
[12:31] <CrazyH> I modified the default Firefox launcher to run the command `firefox -P`  <-- start it up in profile selection mode
[12:33] <oerheks> well, make different launchers then?
[12:34] <oerheks> copy .dekstop files to firefoxwhatever.desktop and edit that
[12:35] <CrazyH> Is there decent documentation on the .desktop files somewhere? Maybe a bit about how the process of using them works?
[12:37] <oerheks> our wiki
[12:37] <oerheks> https://help.ubuntu.com/community/UnityLaunchersAndDesktopFiles
[12:44] <CrazyH> Yeah, I think confusion is happening because I used the wrong term
[12:44] <CrazyH> It's not the launches that I care about, it's the "window buttons"
[12:45] <CrazyH> I want to edit the text displayed in the window buttons in real time
[12:51] <BluesKaj> Hi folks
[12:51] <CrazyH> oerheks, https://pasteall.org/pic/5670854bc8d04beaa761615c696d0ed2   Follow the red arrow. Whatever those are called
[12:52] <CrazyH> They're not launchers. I don't think window buttons is correct either
[12:53] <CrazyH> But whatever they are, that's what I want to modify in real time
[12:54] <CrazyH> and, as you can see from that example. I have 3 separate Firefox profiles running. Telling me the title of the current browser tab is useless! I want to modify the text in those [ whatever they ] so that it has the profile name instead
[12:55] <CrazyH> *whatever they are
[13:03] <oerheks> CrazyH, that is a different question, i think you cannot change that text
[13:04] <CrazyH> oerheks, what is proper term for whatever that thing is?
[13:05] <oerheks> tab?
[13:06] <BluesKaj> yeah, looks like tabs
[13:07] <oerheks> so, any tab of firefox is a new instance, good luck automating stuff :-D
[13:07] <multi8>  /exit
[13:49] <CrazyH> oerheks, ok. So how would I find that new instance? Is there an easier way, or do I literally have search /proc/   for it?
[13:53] <other_rick> hello, How do I add plymouth support to the ramdisk?  the update-initramfs excude the plymouth support by unknown reason
[13:59] <clarkk> I've installed vlc via snap. It cannot open files that are on a secondary partition. Apparently this is by design, because of containment. What are the actual rules for this? What is permitted, and what isn't?
[13:59] <oerheks> CrazyH, cannot help you there
[13:59] <clarkk> It works from my desktop. So that I don't have to copy and paste it all over my filessytems to work out what should work and what shouldn't, could someone explain the rules?
[14:00] <oerheks> clarkk, check out softwarecenter > installed > vlc > permissions
[14:00] <oerheks> oh, is ee they don't give extra permissions for vlc
[14:02] <clarkk> oerheks, thanks. It allows read and write to the home folder, and to removable storage devices. My files are on another partition.  This is a really bad limitation
[14:02] <clarkk> oerheks, is there such a snap permission of, "allow read and write from other partitions"?
[14:02] <oerheks> snap connect vlc:removable-media
[14:02] <clarkk> oerheks, it's a hard drive tho, in my computer
[14:05] <oerheks> hmm, here it does open any other harddrive from the 'open file' menu
[14:06] <oerheks> or 'folder'
[14:09] <leftyfb> clarkk: you can try installing the snap with --devmode
[14:10] <clarkk> oerheks, interestingly, I cannot see the mount point for the partition, when I go to File...
[14:11] <oerheks> + other location > choose hdd
[14:13] <clarkk> oerheks, I can't find that option
[14:14] <oerheks> open file.. > + other location > choose hdd
[14:15] <oerheks> really, so simple?
[14:16] <clarkk> oerheks, there really isn't that option on mine
[14:21] <leftyfb> clarkk: you can try installing the snap with --devmode
[14:26] <clarkk> oerheks, leftyfb thanks for your help.  I'll try some of your suggestions
[14:34] <zChris90> If a software creates a user when it is installed. Why is that user not removed when i remove the software ? The software im talking about is zammad
[14:35] <EriC^^> zChris90: did you try purging it?
[14:35] <zChris90> yes
[14:36] <zChris90> its the same with its services
[14:36] <zChris90> they still linger around
[14:38] <oerheks> if an application creates a user, and you removed that app, did you logout/login after that?
[14:38] <zChris90> yeah i rebooted
[14:39] <oerheks> where does zamman come from? any guide / deinstall guide they provide?
[14:39] <oerheks> it is not in our repos
[14:39] <zChris90> zammad
[14:39] <oerheks> oh sorry, typo, but still not in our repos
[14:40] <zChris90> Ah then i have added it from https://docs.zammad.org/en/latest/install/ubuntu.html
[14:42] <EriC^^> zChris90: if you absoutely want to remove the user you could do 'sudo userdel -r <user>'
[14:42] <EriC^^> absolutely*
[14:43] <zChris90> yeah im doing that now
[14:48] <ldiamond> I'm trying to unlock and change the password of my "passwords" in seahorse but there's no popup when I click "unlock" or "change password". Is there something missing? The application asking for password?
[14:52] <EriC^^> ldiamond: maybe try starting seahorse in the terminal to see any relevant output it may give
[14:52] <reith> Hi, what user `proxy' is for in default ubuntu installation?
[14:57] <ldiamond> EriC^^: yea I did that but there's nothing that makes any sense to me. Only warnings: gtk_icon_theme_choose_icon_for_scale: runtime check failed: ((flags & GTK_ICON_LOOKUP_GENERIC_FALLBACK) == 0)
[14:57] <ldiamond> There's this but what I found online says it doesn't matter: seahorse-Message: 09:25:22.843: DNS-SD initialization failed: Daemon not running
[14:59] <ldiamond> All Gnome applications take ages to load as well, as if it's waiting on something until a timeout
[14:59] <kirk781> It's waiting for you to switch to Xfce :p
[15:02] <TheBigK> let the desktop start fight. Plasma is the way to go, hello btw :)
[15:02] <kirk781> Choosing b/w Gnome and Plasma is like stuck b/w a rock and a hard place
[15:02]  * kirk781 loves Budgie
[15:04] <ldiamond> kirk781: I don't use Gnome. But some of the applications I have are gnome and I haven't found an alternative yet
[15:04] <kirk781> ldiamond, which ones?
[15:04] <ldiamond> Awesomewm
[15:04] <kirk781> Isn't that a window manager and independent of Gnome?
[15:05] <ldiamond> It's my work computer so it comes with all the gnome stuff
[15:05] <ldiamond> yes it's independent of gnome. I just start it with `startx`/xinit
[15:05] <zChris90> cant you login to gnome and change the password from there?
[15:06] <kirk781> You're lucky. Most work computers are stuck with Windows or Stallman forbid, Big Sur
[15:06] <ldiamond> zChris90: lol, yes, but that's not an acceptable solution.
[15:06] <ldiamond> I had a brand new MBP given to me first day. I returned it so they send me a 10 year old used laptop with linux.
[15:07] <zChris90> :|
[15:07] <ldiamond> I'm happier.
[15:07] <kirk781> I respect you. As a person who lost two friends to the environment of Apple; I know
[15:07] <kirk781> When he told me he switched from Windows; I was so happy. Sadly, my heart broke when the alternative turned to be a Macbook
[15:08] <withered_wolf> I'm on a MBP right now - but also have my trusty linux box spun up beside me, too.
[15:08] <lotuspsychje> !discuss
[15:08] <kirk781> Linux can't be installed on new M one chips right now, right?
[15:08] <oerheks> let get back to support only, thanks
[15:09] <oerheks> kirk781, indeed, but work is in progress.
[15:10] <ldiamond> Ok, Archlinux's /etc/X11/xinit/xinitrc.d/50-systemd-user.sh got the answer for me!
[15:32] <tete_> hi, running xubuntu 20.10, i tried to convert a .jpg to .pdf which aborts with an error: convert-im6.q16: attempt to perform an operation not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/408.
[15:32] <tete_> anyone an idea how to get rid of that message?
[15:33] <tete_> i already added   <policy domain="coder" rights="read | write" pattern="PDF" /> like described in https://stackoverflow.com/questions/52998331/imagemagick-security-policy-pdf-blocking-conversion
[15:46] <other_rick> Which package provides the plymouth-set-default-theme?
[15:55] <leftyfb> other_rick: There are no official ubuntu packages that provide that file
[15:59] <Lope> does Ubuntu have an AMD OpenCL driver that I can "just install" and "just works" ?
[16:04] <Hamidreza> Hi guys, I want to use rsync without getting password to it using command promt and I want to pass password to rsync using a file, How can I do it?
[16:05] <leftyfb> Hamidreza: use ssh keys
[16:06] <Hamidreza> leftyfb, I dont want to use ssh, just I want to pass key to rsync using a file
[16:06] <leftyfb> Hamidreza: why?
[16:06] <Hamidreza> because I must :)
[16:07] <leftyfb> Hamidreza: why?
[16:07] <Hamidreza> leftyfb, acctually I wanted to send file to 10 servers using scp but without password and ssh key
[16:08] <leftyfb> Hamidreza: why without an ssh key? That is less secure and not as easily setup
[16:08] <Hamidreza> (I dont want let other ssh to server )
[16:09] <Hamidreza> leftyfb, If I copy ssh key to my servers , others can ssh to my server without password
[16:09] <Hamidreza> I read that we have sshpass
[16:09] <leftyfb> Hamidreza: only if they have the private key. If you don't give anyone else the private key, nobody else can login using the ssh key
[16:09] <Hamidreza> but its not good (I dont want to install other tools to do that)
[16:10] <leftyfb> Hamidreza: rsync/scp using SSH and ssh keys is your easiest and most secure method
[16:10] <Hamidreza> leftyfb, they have my private key
[16:10] <leftyfb> Hamidreza: you have yet to give a good reason to do it any other way
[16:10] <leftyfb> Hamidreza: then that is a very poor security policy
[16:10] <leftyfb> Hamidreza: use a different keypair
[16:13] <Hamidreza> leftyfb, If I want another person do this for me
[16:13] <leftyfb> Hamidreza: use a different keypair and don't give anyone else the private key. That defeats the purpose of "private" keys
[16:13] <leftyfb> Hamidreza: then have them setup their own keypair
[16:14] <Hamidreza> for example I want my programmer could scp to 10 servers but they shouldn't have ssh access
[16:14] <Hamidreza> leftyfb, How can I solve this problem?
[16:15] <leftyfb> Hamidreza: shouldn't have ssh access or shouldn't have login access?
[16:15] <Hamidreza> leftyfb, is there any difference between them?
[16:15] <leftyfb> Hamidreza: you can setup their local account to not have login access. I think you can also setup their ssh account to only allow scp and not login
[16:15] <Hamidreza> I can not understand it
[16:16] <Hamidreza> what is difference between ssh access and login access?
[16:17] <leftyfb> Hamidreza: you can start by setting their user shell to "/bin/nologin". Though there are ways around that. Maybe also look at https://www.thomaslaurenson.com/blog/2018-09-07/restricting-ssh-access-using-rssh/
[16:21] <Hamidreza> leftyfb, How can I say to my servers that this account hasn't login permission?
[16:21] <leftyfb> Hamidreza: you edit the user shell
[16:22] <leftyfb> Hamidreza: https://www.tecmint.com/change-a-users-default-shell-in-linux/
[16:24] <Hamidreza> I think there is missunderstanding, thought that we have pc1 that all programmers have login permission to it and they should have the ability of copying file to 10 servers but not login to those servers
[16:24] <Hamidreza> How can I set this?
[16:25] <leftyfb> Hamidreza: on the servers, follow the instructions I specified above
[16:26] <Hamidreza> leftyfb, you mean rssh?
[16:26] <leftyfb> Hamidreza: and/or set the shell to nologin
[16:30] <Bozdoc84> hi all
[16:30] <Hamidreza> leftyfb, I do ssh-copy-id to servers but there is no user in /etc/passwd on 10 servers!
[16:30] <Hamidreza> (to change shell)
[16:31] <oerheks> Hamidreza, sounds like 'they' have ssh access without root access configured?
[16:32] <Hamidreza> oerheks, yes they are normall user that have access to share pc
[16:32] <leftyfb> Hamidreza: create users? You were originally asking about rsync/scp access to said servers using a password. I assume that means you currently have the ability to remotely manage these servers properly. Setup user accounts, each with "/bin/noglin" as their shell and setup individual ssh keypairs for each user
[16:49] <SteelRose> Hi all! I'm trying to use lineinfile to replace a few placeholders in a Tomcat application - you can see some excerpts here https://pastebin.com/KfqEUEHc - for some reason, my regex does not seem to be working... the basic idea is to replace the placeholders after the "=" sign with the values defined in each variable... Thanks !
[16:55] <leftyfb> SteelRose: you want #ansible
[17:00] <SteelRose> leftyfb: already tried there.. I also asked here just in case someone else knew
[17:07] <acebrianjuan> Hi, I have a machine with Ubuntu 18.04 and Win10 (dual boot). I realized that I need more space for Ubuntu and I would like to take it from the Windows partition. Is is possible to readjust OS partitions?
[17:12] <oerheks> acebrianjuan, yes, let windows make the freespace itself, with diskmanagment. then boot the live iso, and you can use disks graphically to drag the partition boundy.
[17:12] <oerheks> then
[17:12] <oerheks> update grub, as the partition UUID has changed
[17:13] <acebrianjuan> oerheks: ok, so first I have to free up space by booting onto Windows
[17:13] <oerheks> yes, that saves you a lot of headache.
[17:14] <oerheks> no windows complaining, antivirus and such.
[17:15] <acebrianjuan> ok, then I boot into a Ubuntu live usb iso and assign the free space to the Ext4 Linux Filesystem
[17:15] <acebrianjuan> correct?
[17:15] <acebrianjuan> oerheks: ^
[17:17] <acebrianjuan> oerheks: how do I update GRUB?
[17:17] <lotuspsychje> sudo update-grub
[17:18] <lotuspsychje> !dualboot | acebrianjuan
[17:19] <acebrianjuan> ok, thanks guys
[17:20] <oerheks> one needs to chroot into the installation, to update boot; https://itectec.com/ubuntu/ubuntu-how-to-run-update-grub-from-a-livecd/
[17:21] <acebrianjuan> oerheks: oh, so updating grub is done from the live usb as well?
[17:22] <oerheks> sure
[17:23] <oerheks> but if your installation is fresh, one could consider reinstall.
[17:24] <acebrianjuan> no, my installtion is not fresh I need to keep the stuff that I have (specially on the Ubuntu partition)
[17:28] <lotuspsychje> always make a backup
[17:31] <acebrianjuan> lotuspsychje: doing that now :)
[17:44] <halvors> Why is the mainline-kernel ppa no succeding building amd64 builds for 5.11.2 and 5.11.3?
[17:46] <rajivmars> I m using ubuntu20.04. as i m new to linux, i am reading debian-reference. that manual says that there are six switchable virtual character consoles and normally the x-window is running on the virtual console 7. following the manual when i am trying to go to tty1 by using ctrl+alt+f1 (or f2), its not working. but i can go to tty3 by using f3 instead of f1 or f2. thereafter, when i am trying to come to GUI by using alt+f7, i got nothing.
[17:46] <rajivmars> instead alt+f2 get the GUI back. why is it happening? is is normal or something goes wrong?
[17:46] <leftyfb> halvors: maybe ask in #ubuntu-dev or #ubuntu-kernel
[17:46] <halvors> leftyfb: thx
[17:47] <lotuspsychje> !tty | rajivmars
[17:49] <rajivmars> ubottu: is it ok or something went wrong?
[17:53] <ash_worksi> is the generally favored VPN client in the world of ubuntu openvpn?
[17:55] <ldiamond> ash_worksi: Depends on the vpn server.
[17:55] <ldiamond> If you control both the server and the client, my personal preference is wireguard.
[17:56] <ldiamond> Note that wireguard's security hasn't gone through as many audits as openvpn for example, but imo it's damn neat.
[17:57] <ldiamond> It's simplicity is a good argument in favor of its security.
[18:49] <r21> Hi everyone, I need urgently help with my pc (I need it tomorrow for school), it cannot find the wifi adapter, I tried everything, but I cannot manage to make it works, please contact me privately
[18:50] <r21> Also, sorry for the bad grammar, I'm not anglophone
[18:51] <lotuspsychje> r21: sudo lshw -C network to see if driver is loaded
[18:51] <r21> let me do it
[18:51] <leftyfb> r21: we do not provide private help here. All support gets done in this channel
[18:51] <r21> Sorry
[18:51] <r21> I'll mask my data then
[18:51] <r21> This is the output:
[18:52] <r21> Wai
[18:52] <r21> t
[18:52] <r21> Do I have to put it on pastebin (for avoid "spamming")?
[18:52] <r21> leftyfb
[18:52] <leftyfb> r21: yes, please use pastebin
[18:52] <r21> Great
[18:53] <r21> lotuspsychje Here's the output: https://pastebin.com/jERy5r4v
[18:54] <lotuspsychje> r21: unclaimed, meaning your driver isnt loaded indeed
[18:54] <r21> So I have to use modprobe?
[18:55] <lotuspsychje> r21: wich ubuntu release and kernel version are you currently on?
[18:55] <r21> I'm on Ubuntu 20.04 Latest (just finished doing all the updates)
[18:55] <r21> Now, let me see the kernel
[18:56] <r21> 5.8.0-44-generic
[18:56] <lotuspsychje> r21: did your wifi work at ubuntu setup?
[18:57] <r21> No, I'm using ethernet via USB
[18:57] <r21> Even audio wasn't working, but it fixed after doing all the updates
[18:58] <jeremy31> lotuspsychje:  I don't think that has kernel support, likely needs rtl8821ce-dkms if it's patched for 5.8
[18:59] <lotuspsychje> jeremy31: he needs the git to make it work?
[18:59] <jeremy31> tomaspinho has a github for it
[19:00] <r21> I already have git installed, I used it for trying to install the drivers
[19:00] <r21> I think I installed the wrong ones
[19:02] <Maik> r21: how long do you have ubuntu installed? Since today or longer?
[19:02] <r21> Yes, a couple of hours
[19:02] <Maik> ouch
[19:02] <Maik> if you know you need it for school tomorrow why did you even do it...
[19:03] <r21> I have another PC, but this is my primary one (for school)
[19:03] <r21> I'm already familiar with ubuntu, my desktop pc never gave me a problem
[19:04] <Maik> let's hope you are able to get it fixed then. :)
[19:04] <r21> Yes :)
[19:06] <lotuspsychje> r21: a few options, try the git jeremy31 adviced, install ubuntu from a 5.4 kernel iso as a test, try !mainline higher kernel(s) as a test
[19:07] <r21> How can I downgrade the kernel?
[19:08] <lotuspsychje> r21: downgrade isnt an option, only go higher or if you have previous kernels in your list, boot them at grub (as a test)
[19:08] <r21> Ok, let me connect from an another device
[19:09] <r21> Another thing, this PC doesn't have dual boot, how do I start using grub?
[19:09] <lotuspsychje> hold shift at boot r21
[19:09] <r21> good
[19:10] <ash_worksi> ldiamond: thanks for the suggestion
[19:10] <lotuspsychje> r21: but if you say your install is recent, you might only have 5.8 kernel
[19:10] <r21> Yes
[19:10] <r21> I think so
[19:11] <r21> So, what can I do?
[19:12] <lotuspsychje> r21: see the options i gave you above
[19:13] <r21> Ok, do I need to reinstall the system, or I can try using the wifi in live testing?
[19:17] <oerheks> enable universe repository, and install rtl8821ce-dkms ; and reboot
[19:18] <oerheks> https://launchpad.net/ubuntu/+source/rtl8821ce
[19:19] <Maik> oerheks: isn't universe enable by default after installing the system?
[19:19] <oerheks> not sure..
[19:19] <Maik> it was at my end
[19:19] <oerheks> not during install, AFAIK
[19:20] <lotuspsychje> r21: <oerheks> enable universe repository, and install rtl8821ce-dkms ; and reboot
 https://launchpad.net/ubuntu/+source/rtl8821ce
[19:24] <r21> lotuspsychje I downloaded the package, how do I build and install it?
[19:25] <oerheks> sudo apt update && sudo apt install rtl8821ce-dkms
[19:25] <oerheks> i just posted the url to show the package is there
[19:26] <r21> Good
[19:26] <r21> Let me reboot
[19:29] <r21> It still can't find the adapter
[19:32] <r21> Should I go for another distribution?
[19:41] <ghaoil> I install zfs-2.0.3 from the PPA but kmod zfs-kmod-0.8.3-1ubuntu12.6 is loaded. Can I unload that module and load the one built by zfs-dkms?
[19:42] <ghaoil> I can only import my pool in read-only mode.
[19:52] <oerheks> r21 what is the output now, of sudo lshw -C network
[19:56] <r21> let me see
[19:57] <r21> oerheks https://pastebin.com/QHVb7neT
[20:03] <oerheks> no idea why the driver is not loader. is this an UEFI / secure boot machine?
[20:06] <r2132> rauldux: yes
[20:32] <ducasse> ghaoil: the module provided by dkms should take priority over the one supplied by the os
[20:33] <ghaoil> ducasse, yes, but it doesn't somehow. I don't have secure boot enabled.
[20:34] <ghaoil> I've stopped zfs-zed and removed the module.
[20:34] <ducasse> try loading it with insmod
[20:35] <ghaoil> ducasse: "Unknown symbol in module"
[20:36] <ducasse> try running depmod -a
[20:37] <ducasse> ghaoil: did you unload spl as well?
[20:41] <ghaoil> ducasse, tried that just now. Same symbol error.
[20:42] <ducasse> zfs depends on other modules, you likely need to reload those as well
[20:51] <Lope> how can I get the ubuntu keyring, so I can debootstrap it?
[21:18] <Swift110-mobile> hey all
[21:34] <Lope> by default does ubuntu have /etc/apt/apt.conf ?
[21:36] <oerheks> interesting
[21:43] <leftyfb> Lope: no. Why?
[21:43] <Lope> leftyfb, just asking
[21:44] <oerheks> in #debian you ask for adding the ubuntu gpg key ..
[21:44] <oerheks> must be monday
[21:45] <Elw3> Hey, can someone point me to what to do when quemu fails to find kvm?
[21:48] <oerheks> Elw3, pastebin your command and error output, could help
[21:49] <eelstrebor> is there a utility for determining whether WPA2 or WPA3 is actually being used?
[21:50] <eelstrebor> ubuntu 20.04
[21:50] <Elw3> Well its literally Could not access KVM module: No such file or directory
[21:52] <sarnold> Elw3: paste the output of kvm-ok  ?
[21:54] <Elw3> waiting for apt to finish....
[21:55] <leftyfb> sarnold: cpu-checker isn't installed by default on 18.04. My 20.04 machine isn't booted yet to check
[21:56] <sarnold> oh strange, I really expected that to be there :)
[21:57] <Elw3> Oh i was waiting for synaptic but there was a confirmation message hidden all the time.
[22:00] <Elw3> Ahaaa  KVM (svm) is disabled by your BIOS
[22:00] <Elw3> Thanks, thats straight forward
[22:00] <sarnold> yay :D
[22:09] <Lope> is there a meta package for linux kernel 5.4?
[22:10] <Lope> I see linux-image generic is an old kernel.
[22:10] <oerheks> Lope, you are still on that debian kernel?
[22:11] <Lope> oerheks, no, I only used debian to debootstrap an ubuntu
[22:11] <Lope> what meta package can I install for 5.4 on Bionic?
[22:12] <Lope> looks like linux-image-oem is good
[22:13] <sarnold> Lope: try linux-generic linux-tools-generic
[22:13] <leftyfb> Lope: I would go with thw HWE kernel
[22:13] <sarnold> Lope: the oem kernels have a bunchof oddball stuff in it -- if you don't actually need it, it might be better to skip it
[22:13] <leftyfb> !hwe | Lope
[22:13] <oerheks> why not just updating that debootstrapped ubuntu?
[22:13] <leftyfb> Lope: sudo apt install linux-image-generic-hwe-18.04
[22:15] <Lope> leftyfb, sarnold: I want to use AMD OpenCL stuff, what kernel would be good for that?
[22:17] <Lope> sarnold, linux-generic is the old 4.15 kernel
[22:17] <Lope> I want 5.4
[22:17] <Lope> leftyfb, thanks linux-image-generic-hwe-18.04 looks good
[22:24] <Lope> sarnold, leftyfb, oerheks: in debian, you have to install various firmware-linux packages to get hardware working
[22:24] <Lope> do I need to install any similar packages in ubuntu?
[22:24] <leftyfb> Lope: are you having issues with your hardware?
[22:25] <Lope> leftyfb, I haven't booted it yet.
[22:25] <Lope> Oh, I see there's a package called firmware-linux
[22:25] <Lope> it doesn't distinguish free/non free though.
[22:25] <leftyfb> Lope: let us know if you have issues. Though it sounds like this is a very non-standard and potentially unsupported install you have going here
[22:26] <Lope> debootstrap isn't that crazy.
[22:27] <Lope> leftyfb, I see there's no cryptsetup-initramfs package.
[22:27] <leftyfb> Lope: it's not a supported installation method
[22:27] <Lope> I guess it's part of cryptsetup
[22:27] <Lope> that's fine
[22:27] <Lope> Just asking questions about packages.
[23:02] <raffaem2> will X11 be available in 21.04 through the package system?
[23:03] <sarnold> yes, I can't imagine x11 being dropped for a while
[23:09] <raffaem2> I rely on some X11 tools and softwares and don't want to lose it
[23:11] <raffaem2> I see my 20.10 is supported until July 2021. What does it mean?
[23:12] <sarnold> we'll stop preparing security updates for 20.10 after that point
[23:13] <raffaem2> so if I stay with 20.10 I won't get any package update whatsoever after July 2021, right?
[23:13] <sarnold> exactly. at some point you'll get notified that 21.04 has been released, and you should make every effort to click that "upgrade" button before july 2021
[23:14] <raffaem2> ("we" means you work for Canonical?)
[23:14] <sarnold> yes
[23:16] <raffaem2> I see 20.04 LTS is supported until April 2025
[23:17] <raffaem2> If I install 20.04, will I get all updates (security or new features) until April 2025? Or only security updates?
[23:18] <jeremy31> If you don't install, you will never know
[23:19] <raffaem2> that's why I want to be taught
[23:20]  * raffaem2 is asking for a Ubuntu mentor
[23:21] <raffaem2> It took some time to configure my system and don't want it to break every 6 months ....
[23:26] <raffaem2> so?
[23:26] <raffaem2> said otherwise, if I install 20.04 LTS and do "apt-get upgrade", will I get the same system as an updated 20.10?
[23:29] <sarnold> raffaem2: there's also bug fixes, I have less visibility into how often those are released
[23:29] <sarnold> raffaem2: there's mail lists that keep track of all the updates made in each release, eg https://lists.ubuntu.com/archives/focal-changes/
[23:32] <jeremy31> I have been staying with LTS releases for a while
[23:33] <sarnold> yes, sticking with LTS releases is a great idea for the average user
[23:34] <sarnold> if you like filing bug reports and contributing to the development by testing things, the other releases are fine :) but if you really just want things to work, sticking to the LTS releases is a fine choice
[23:36] <raffaem2> I have installed 20.10 and it is my understanding that downgrading is not a good idea
[23:40] <raffaem2> didn't expect it took so much time for configuration/bug reports
[23:40] <raffaem2> I don't want things to break when upgrading to 21.04
[23:41] <raffaem2> although I should get X11 by default since I have NVIDIA (unfortunately .... will buy AMD next time), if I understood the update correctly
[23:42] <sarnold> raffaem2: yeah, downgrading is not recommended
[23:43] <sarnold> raffaem2: just keep moving forward every six months until you get to the next LTS release
[23:43] <Bashing-om> raffaem2: Nvidia and Wayland still have meshing issues - 21.04 will have X11 as an option at the login screen pull down.
