fluiDI'm SSH'ing into my ubuntu server and my arrow keys don't work. How do I go about debugging this?00:08

fluiDthe up arrow works for bash history00:09
leftyfbamr00t: contact your VPS provider00:10

ubottufluiD: Windows 10 has a feature called Windows Subsystem for Linux, which allows it to run Ubuntu (and other Linux distro) userspace programs without porting/recompliation. For discussion and support, see #ubuntu-on-windows or ##windows. For installation instructions, see https://msdn.microsoft.com/en-us/commandline/wsl/install_guide00:12
fluiDerr, yes, sorry. Ubuntu 20.04 in WSL00:12
leftyfbfluiD: your issue is one of the WSL system, not ubuntu00:13
fluiDleftyfb, the arrow key works in bash but not in less. That's still a WSL problem?00:13
leftyfbfluiD: yes00:13
fluiDleftyfb, 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
fluiDbut thank you very much for trying to help me!!!00:15
kxslI'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?01:00

nop_i want a nvidia-only setup09:46
nop_because vnccserver always seems to use mesa for everything instead of using the gpu09:47
nop_alternatively, seeing that it uses libgldispatch, how can i select an opengl backend in ubuntu?09:47

TimothyPHi, 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 either10:31
TimothyPis there a way to completely reset it10:31
jeremy31TimothyP: Any chance a new kernel was installed before the reboot?10:34
TimothyPoh yes10:35
TimothyPit upgrade the kernel with software updates10:35
TimothyPmessed up my nvidia drivers (famous black screen)10:35
TimothyPand came back without interfaces10:35

TimothyPno packages found matching linux-modules-extra-5.8.0-44-generic10:38

jeremy31Use grub menu advanced options to boot into an older kernel then>  sudo apt install --reinstall linux-modules-extra-5.8.0-44-generic10:41
TimothyPah ok10:41
TimothyPthank you!10:41
TimothyPanother 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 minutes10:42
TimothyPbtw those missing extra's is that a bug or did I somehow cause it10:43
jeremy31TimothyP: I don't know why it happens as it doesn't happen a lot10:44

StupidDanboWhat opens the file browser when you open/saveas in an application? Is that controlled by the "desktop environment"?10:54
StupidDanbobecause 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.10:55
TimothyPapparently it's waiting for crond10:56
lotuspsychjeTimothyP: do you have some cron scripts active?10:59
TimothyPthis is basically a clean install with some software added (vscode, mono, dotnet, godot, blender, firefox, edge, gimp, etc...)11:02

StupidDanboI don't know what to search for. I'm using plain English searches like [Ubuntu "what opens files in programs"] and no luck.11:05
TimothyPspooky :D but will have a look11:06
TimothyPSutpidDanbo does this help11:07
TimothyPI searched for "linux list open files"11:07
TimothyPoh misread the question11:08
TimothyPActually when we request an OpenFileDialog we can specify the location (that means the app controls it)11:09
StupidDanboApparently the thing that displays the file browser in EVERY program that can "open file", is different from the normal OS file browser.11:09
TimothyPWell there are multiple ways to get an Open File dialog11:10
StupidDanboIt'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.11:10
StupidDanboI just want folders to display first.11:11
TimothyPthe UI framework you are using might provide its own implementation or the app might be calling the native OS API's like OpenFileDialogEx on Windows11:11
StupidDanboI already have folders displaying 1st in the normal OS file browser, but every program that saves files doesn't use that.11:11
TimothyPthe latter requires specific implementations for each platform so usually the UI framework provides it11:11
StupidDanbo"UI framework" Is that what I'm looking for?11:12
TimothyPdepends on what you are trying to do11:12
StupidDanboI want firefox to display folders 1st when I save files.11:12
TimothyPImagine 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
TimothyPbut given that info... what can you do11:13
StupidDanboI don't know. I'm not familiar with the terms so I don't know what to look for.11:13
TimothyPinteresting I never stopped to think about it, going to try saving a file now in firefox11:13
TimothyPhang on11:13
StupidDanbomaybe "OS API" if not "UI framework"11:13
StupidDanboI thought I could sort by file size, but apparently folders aren't sorted that way.11:14
TimothyPhmm in my firefox on ubuntu I see folders before files11:14
TimothyPand it's using the SaveFileDialog provided by ubuntu/gnome11:15
TimothyPnot a custom one11:15
TimothyPah and there is an option for what you want hang on11:15
TimothyPwhen saving a file in firefox , right click anywhere then select Sort folders before files11:17
TimothyPdoes that help you?11:17
StupidDanboI dunno. lemme see if I can find that. I'm in Xubuntu.11:17
TimothyPnot sure, ubuntu is using the GNOME desktop environment and you are using the Xfce desktop environment11:18
StupidDanbobut I already have my OS's file browser set to display folders 1st.11:19
TimothyPI searched for "Xfce file open dialog sort folders before files" to give you an idea of what I search for11:19
StupidDanbooh 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
StupidDanboOMG IT WORKS! THANK YOU!11:23
StupidDanboI don't even know how long I've had to deal with it unsorted.11:23
StupidDanboprobably many years.11:23
TimothyPthings 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 type11:24
StupidDanbooh, did I make the right decision in picking XFCE over Gnome?11:25
TimothyPdo you like Xfce ?11:26
StupidDanboI 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
TimothyPif you like it, you did not make the wrong decision11:26
TimothyPEveryone has their own preference11:26
StupidDanboI don't even know how it varies. :>11:26
TimothyPUbuntu's GNOME makes me feel relaxed while working11:26
TimothyPwhereas Windows 10 stresses me out11:26
TimothyPand MacOS makes me want to pick up my mouse and throw it out the window11:27
TimothyPKDE makes me feel like I'm in a candy store11:27

lotuspsychjekeep it ontopic please guys11:27

CrazyHUbuntu 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?12:13
CrazyHAlso... not sure if I'm using the correct terminology, but hopefully I'm being clear enough to show what I mean :-/12:14
=== Bebef6 is now known as Bebef
CrazyHin 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.12:19
CrazyHFor me this would be SUPER helpful, because I run like 6 Firefox windows at a time, all on different profiles12:20
oerhekssudo nano  /usr/share/applications/firefox.desktop12:20
oerheks..wait, 6 different profiles :-D12:20
oerhekswhy commandline?12:20
CrazyHBecause 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 automatically12:21
oerheksone can change the launcher description, not the title of the webpage opened.12:22
CrazyHThat's fine. The launcher description is all I care about. Maybe if I could also change the launcher icon... that would be awesome too12:23
oerheksit's all in the desktop file12:24
CrazyHBut 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 instance12:24
CrazyHWell, something is odd. I have 3 instances of firefox running now, but only 1 firefox.desktop file12:27
CrazyHIt looks like it is mostly language options?12:27
lotuspsychjeone is snap?12:27
oerheksthey all using the same desktop file.12:28
oerheksso if you start firefox with different profiles, how did you do that?12:29
CrazyHI modified the default Firefox launcher to run the command `firefox -P`  <-- start it up in profile selection mode12:31
oerhekswell, make different launchers then?12:33
oerhekscopy .dekstop files to firefoxwhatever.desktop and edit that12:34
CrazyHIs there decent documentation on the .desktop files somewhere? Maybe a bit about how the process of using them works?12:35
oerheksour wiki12:37
CrazyHYeah, I think confusion is happening because I used the wrong term12:44
CrazyHIt's not the launches that I care about, it's the "window buttons"12:44
CrazyHI want to edit the text displayed in the window buttons in real time12:45
BluesKajHi folks12:51
CrazyHoerheks, https://pasteall.org/pic/5670854bc8d04beaa761615c696d0ed2   Follow the red arrow. Whatever those are called12:51
CrazyHThey're not launchers. I don't think window buttons is correct either12:52
CrazyHBut whatever they are, that's what I want to modify in real time12:53
CrazyHand, 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 instead12:54
CrazyH*whatever they are12:55
oerheksCrazyH, that is a different question, i think you cannot change that text13:03
CrazyHoerheks, what is proper term for whatever that thing is?13:04
BluesKajyeah, looks like tabs13:06
oerheksso, any tab of firefox is a new instance, good luck automating stuff :-D13:07

oerheksclarkk, check out softwarecenter > installed > vlc > permissions14:00
oerheksoh, is ee they don't give extra permissions for vlc14:00
clarkkoerheks, 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 limitation14:02
clarkkoerheks, is there such a snap permission of, "allow read and write from other partitions"?14:02

HamidrezaHi 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?16:04
leftyfbHamidreza: use ssh keys16:05
Hamidrezaleftyfb, I dont want to use ssh, just I want to pass key to rsync using a file16:06
leftyfbHamidreza: why?16:06
Hamidrezabecause I must :)16:06
leftyfbHamidreza: why?16:07
Hamidrezaleftyfb, acctually I wanted to send file to 10 servers using scp but without password and ssh key16:07
leftyfbHamidreza: why without an ssh key? That is less secure and not as easily setup16:08
Hamidreza(I dont want let other ssh to server )16:08
Hamidrezaleftyfb, If I copy ssh key to my servers , others can ssh to my server without password16:09
HamidrezaI read that we have sshpass16:09
leftyfbHamidreza: only if they have the private key. If you don't give anyone else the private key, nobody else can login using the ssh key16:09
Hamidrezabut its not good (I dont want to install other tools to do that)16:09
leftyfbHamidreza: rsync/scp using SSH and ssh keys is your easiest and most secure method16:10
Hamidrezaleftyfb, they have my private key16:10
leftyfbHamidreza: you have yet to give a good reason to do it any other way16:10
leftyfbHamidreza: then that is a very poor security policy16:10
leftyfbHamidreza: use a different keypair16:10
Hamidrezaleftyfb, If I want another person do this for me16:13
leftyfbHamidreza: use a different keypair and don't give anyone else the private key. That defeats the purpose of "private" keys16:13
leftyfbHamidreza: then have them setup their own keypair16:13
Hamidrezafor example I want my programmer could scp to 10 servers but they shouldn't have ssh access16:14
Hamidrezaleftyfb, How can I solve this problem?16:14
leftyfbHamidreza: shouldn't have ssh access or shouldn't have login access?16:15
Hamidrezaleftyfb, is there any difference between them?16:15
leftyfbHamidreza: 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 login16:15
HamidrezaI can not understand it16:15
Hamidrezawhat is difference between ssh access and login access?16:16
leftyfbHamidreza: 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/16:17

Hamidrezaleftyfb, How can I say to my servers that this account hasn't login permission?16:21
leftyfbHamidreza: you edit the user shell16:21
leftyfbHamidreza: https://www.tecmint.com/change-a-users-default-shell-in-linux/16:22
HamidrezaI 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 servers16:24
HamidrezaHow can I set this?16:24
leftyfbHamidreza: on the servers, follow the instructions I specified above16:25
Hamidrezaleftyfb, you mean rssh?16:26
leftyfbHamidreza: and/or set the shell to nologin16:26
Bozdoc84hi all16:30
Hamidrezaleftyfb, I do ssh-copy-id to servers but there is no user in /etc/passwd on 10 servers!16:30
Hamidreza(to change shell)16:30
oerheksHamidreza, sounds like 'they' have ssh access without root access configured?16:31
Hamidrezaoerheks, yes they are normall user that have access to share pc16:32
leftyfbHamidreza: 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 user16:32
SteelRoseHi 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 !16:49
leftyfbSteelRose: you want #ansible16:55
SteelRoseleftyfb: already tried there.. I also asked here just in case someone else knew17:00
acebrianjuanHi, 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?17:07
oerheksacebrianjuan, 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
oerheksupdate grub, as the partition UUID has changed17:12
acebrianjuanoerheks: ok, so first I have to free up space by booting onto Windows17:13

rajivmarsI 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
rajivmarsinstead alt+f2 get the GUI back. why is it happening? is is normal or something goes wrong?17:46

ash_worksiis the generally favored VPN client in the world of ubuntu openvpn?17:53
ldiamondash_worksi: Depends on the vpn server.17:55
ldiamondIf you control both the server and the client, my personal preference is wireguard.17:55
ldiamondNote that wireguard's security hasn't gone through as many audits as openvpn for example, but imo it's damn neat.17:56

r21Hi 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 privately18:49

r21let me do it18:51
leftyfbr21: we do not provide private help here. All support gets done in this channel18:51
r21I'll mask my data then18:51
r21This is the output:18:51
r21Do I have to put it on pastebin (for avoid "spamming")?18:52
leftyfbr21: yes, please use pastebin18:52
r21lotuspsychje Here's the output: https://pastebin.com/jERy5r4v18:53
lotuspsychjer21: unclaimed, meaning your driver isnt loaded indeed18:54
r21So I have to use modprobe?18:54
lotuspsychjer21: wich ubuntu release and kernel version are you currently on?18:55
r21I'm on Ubuntu 20.04 Latest (just finished doing all the updates)18:55
r21Now, let me see the kernel18:55
lotuspsychjer21: did your wifi work at ubuntu setup?18:56
r21No, I'm using ethernet via USB18:57
r21Even audio wasn't working, but it fixed after doing all the updates18:57
jeremy31lotuspsychje:  I don't think that has kernel support, likely needs rtl8821ce-dkms if it's patched for 5.818:58
lotuspsychjejeremy31: he needs the git to make it work?18:59
jeremy31tomaspinho has a github for it18:59
r21I already have git installed, I used it for trying to install the drivers19:00
r21I think I installed the wrong ones19:00
Maikr21: how long do you have ubuntu installed? Since today or longer?19:02
r21Yes, a couple of hours19:02
Maikif you know you need it for school tomorrow why did you even do it...19:02
r21I have another PC, but this is my primary one (for school)19:03
r21I'm already familiar with ubuntu, my desktop pc never gave me a problem19:03
Maiklet's hope you are able to get it fixed then. :)19:04
r21Yes :)19:04
lotuspsychjer21: 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 test19:06
r21How can I downgrade the kernel?19:07
lotuspsychjer21: 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
r21Ok, let me connect from an another device19:08
r21Another thing, this PC doesn't have dual boot, how do I start using grub?19:09
lotuspsychjehold shift at boot r2119:09
ash_worksildiamond: thanks for the suggestion19:10
lotuspsychjer21: but if you say your install is recent, you might only have 5.8 kernel19:10
r21I think so19:10
r21So, what can I do?19:11
lotuspsychjer21: see the options i gave you above19:12
