Can't launch Visual Studio Code on Ubuntu - linux

I'm running a VM in Azure with Ubuntu 14.04. I've installed XFCE and use X2GO to remote desktop to the machine.
I've downloaded the VS Code and unzipped the files. When I run Code from a terminal I get the following error:
WouterDeKort#UbuntuDev:~/tools/web/visual-studio-code$ ./Code
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
WouterDeKort#UbuntuDev:~/tools/web/visual-studio-code$ [ , [Error: channel closed] ]
Any idea what I'm doing wrong?
DISCLAIMER ;-) I'm a total Linux newby. I've just installed Linux for the first time today and I have no idea what I'm doing ;-)

The work-a-round is in issue 3451. After running this, I was able to launch it from Debian Jessie with LXDE over X2Go.
sudo sed -i 's/BIG-REQUESTS/_IG-REQUESTS/' /usr/lib/x86_64-linux-gnu/libxcb.so.1

I have the same problem using X2GO and LXDE. Works okay (but slowly) using MobaXterm so apparently this is a problem specific to X2GO.

For anyone who still wonder what is the best choice if you want to start Visual Studio Code on a headless Ubuntu - the winning combination is:
Ubuntu Server + xfce + nomachine remote desktop
VS Code starts immediately without any hacks, you can set your resolution however you like, and nomachine is blazingly fast.

Trying to use bash on Windows and got no installed distributions message

I am trying to use bash on Windows 10, but I'm getting this message when tried to run bash:
Windows Subsystem for Linux has no installed distributions.
Distributions can be installed by visiting the Windows Store:
https://aka.ms/wslstore Press any key to continue...
When I go to that url which opens the Windows Store app, there no sign of any Linux distribution there.
My windows version is(as in my right bottom corner of the screen):
Windows 10 Enterprise Insider Preview. Evaluation copy.Build
16215.rs_prerelease.170603-1840
I follow the instructions in this guide Installation Guide and also was watching this video Editing code and files on Windows Subsystem for Linux on Windows 10 from Scott Hanselman, but they didn't get the message of no installed distribution.
Any Help?
When the Windows Store opened, there was no Distro to choose, then I found this command lxrun /install and worked for me as well.
You will get something like this as an output:
C:\WINDOWS\system32>lxrun /install
Warning: lxrun.exe is only used to configure the legacy Windows Subsystem for Linux distribution.
Distributions can be installed by visiting the Microsoft Store:

I'm getting a similar bug after trying to uninstall and reinstall.
For me I had to open a cmd prompt as administrator and run lxrun /install
I get this when I have recently rebooted. If I wait 5 minutes, the problem fixes itself !
The top answers written for this question are more than enough. I just had trouble following them because lxrun command has been depreceated, so I get the error
'lxrun' is not recognized as an internal or external command, operable
program or batch file.
when I try to run this command with cmd.
It has been replaced with wsl command. You can get more info on this issue here - https://github.com/MicrosoftDocs/WSL/issues/425
When you run wsl /install, there is a chance you may still get the error that you had earlier posted in your question. In that case, simply go to the link https://aka.ms/wslstore as you had gone earlier. If you don't see anything coming up, simply search for Ubuntu and install the same. (If you search with the term wsl though, you will get to see other Linux flavors too and then you can download any of your choice)
It seems that the link given in the command doesn't work. Here's the actual link to the microsoft store for Ubuntu.
https://www.microsoft.com/en-nz/store/p/ubuntu/9nblggh4msv6?rtc=1
You have to go to https://aka.ms/wslstore this link and download ubuntu on windows. After that you can use bash on windows.
If you have any problems with running lxrun /install (for example on ltsb Windows version) try manual mode.
First, go to the folder with downloaded .appx file and run following commands (change filename if needed):
Rename-Item ~/Ubuntu.appx ~/Ubuntu.zip
Expand-Archive ~/Ubuntu.zip ~/Ubuntu
After finishing cd into new folder and run ubuntu.exe file. That's it.
If you get this error after installing a distribution using the windows store, and WSL was working previously, you may need to make sure that the LxssManager service is running, since it often stops after a Windows update or a reboot.
Go to services.msc, and search for LxssManager and start it; if it is running already, restart it.
For everyone who is getting
'lxrun' is not recognized as an internal or external command,
operable program or batch file.
or
Windows Subsystem for Linux has no installed distributions.
Distributions can be installed by visiting the Microsoft Store:
https://aka.ms/wslstore
Open microsoft store, install 'Ubuntu' then open the app. This will install ubuntu and later you can use wsl command since lxrun is deprecated
Go to add or remove programs
Install Windows subsystem for Linux
Go to https://aka.ms/wslstore, which will take you to the Microsoft Store
Select and install a Linux distribution
lxrun /install
Works on a Administrator Command Prompt for Windows 10 Professional, Version 1803 Build 17134.165
This installs GNU/Linux by default whereas there is an option to select between:
Ubuntu
openSUSE Leap 42
SUSE Linux Enterprise
Debian GNU/Linux
Kali Linux
If the given link (https://aka.ms/wslstore) works, it openes the windows store for me with an error saying something is wrong on their side and to try again later.
It's actually easier to solve this problem that other solutions listed here. If you run wslconfig /l and if the output is:
Windows Subsystem for Linux Distributions:
Ubuntu (Default)
Just run wslconfig /s Ubuntu to set Ubuntu as default again. It should start working now.
Edit:
I've also found that if this problem occurs on a fresh boot, then you just wait for a few minutes (10 minutes max) and this error automatically disappears.
Edit 2:
I've also found that this error is sometimes also due to the corresponding service not running. Run CMD as administrator and run
net start LxssManager
For running bash on windows ubuntu is required to be installed.
As you've already added bash from programs and features, now you need to install Ubuntu. Contrary to what is seen in most of the installation guides on web, it does not gets installed by running 'bash.exe'.
You can simply go to Microsoft store in search for 'Bash' or 'Ubuntu'and install Ubuntu 18 LTS from there.
After installation you'll be able to use the terminal and all its commands.
Run the bash command in git bash windows. It worked !!
As of 2022, New Linux distributions are available for Windows 10 as well as Windows 11 like Kali Linux and Ubuntu. Both available from Microsoft Store. Someone watching this question now can visit Microsoft Store to Download them..
I had this same issue. But when you go to the windows store you can search for ubuntu and then install the ubuntu app and it works. I think most of the tutorials on the net are from the beta version and have afterwards never been updated.
https://insights.ubuntu.com/2017/07/11/windows-10-loves-ubuntu-loveislove/
Note: This is also old. You do not need to be on the insider builds. I'm not and it worked.
The only thing that worked for me is described here https://learn.microsoft.com/en-us/windows/wsl/install-manual#downloading-distros
https://aka.ms/wsl-ubuntu-1804
manually install it or run Add-AppxPackage.\.appx from PowerShell
The link to the store appears to have a region lock in it, resulting in errors for many visitors.
However there are different Ubuntu distributions to be downloaded. See image below, image is however in Dutch but it will show results.
So pick a version you desire and it will result in a working bash.
The actual answer to the question query is: The user exists with Ubuntu already installed. But WSL command does not find anything in CMD.exe "Command Line" "System does not find distribution."
You need to start the below WSL command from Windows Start Menu. And then the old Linux System will show up on WSL in the command line as found.
If this doesn't work for you? Just start up PowerShell with Administrator and:
WSL --help
WSL "only this command, will start the Linux default distro selected"
You can then start up using this command with CMD.exe Administrator in Windows:
lxrunoffline l "This will now list all your distros"
With an option to remove old distros copied to Windows folders are with perhaps Ubuntu18.04 such way that you will have to use Linux to remove older folders, do not try to copy or edit files in a distro with Windows Apps. You risk integrity problems as well as many errors followed by huge processing time. Use folder /mnt to find your drive with Linux and use commands there to further finish your work as perhaps copying the home directory into a new distro.
My solution to move "not copy" my distro then was: "to give space for C:"
lxrunoffline m -n Ubuntu-18.04 -d d:\wslinstalled\Ubuntu-18.04 "remember folder names"
"Remember folder name such as Ubuntu-18.04 for a specific movement. Unless you will overwrite everything on that folder name with also the lxrunoffline files and you risk losing older copies if you use one folder name. You might end up with a strange name to your project if you just use one directory."
Lxrunoffline has several other commands if you need help just run:
lxrunoffline
like beginner_ said in his answer you need to go to the store and look for the distros you want to install.
Please see the following link to understand what has changed and what you can excpect or what distros you can look for(the list is outdated so just try to find an updated list or just try your luck).
I am running on my machine without the developer mode Ubuntu, OpenSuse and Kali.
Access to Microsoft Store is blocked by my company. For me following worked in PowerShell (admin) -
lxrun /install
Go to cmd, and then run the following command:
lxrun /install
Typing lxrun /install in elevated command prompt works....
The solution to the error "WSL 2 installation is incomplete",
Execute the following steps:
wsl --install -d Ubuntu ## lxrun is no more, its now replaced with wsl,

QXcbConnection: Could not connect to display Aborted, when installing QT on linux

I am trying to install Qt on a Linux machine remotely from a Windows machine using PuTTY.
When I run the command to install Qt on Linux I get the following error:
~/QT# ./qt-unified-linux-x64-2.0.4-online.run
QXcbConnection: Could not connect to display
Aborted
Please suggest any workaround.
You can use the software repository of that Linux distribution.
For example, if it's Debian or Ubuntu:
sudo apt-get install qtbase5-dev
But if you really want to use the installer (usually, when specific Qt version is needed), then try one of the options:
run an X server on that machine
use the --script option of the online installer (you'll have to write a script like here: https://stackoverflow.com/a/34032216/4742108), it will probably need UI anyways
see if the offline installer has an option to run without UI
refer to here: https://community.nxp.com/message/532966
maybe use the cmd "export DISPLAY=:0" and it works
Try to connect with ssh to the host machine using -X to enable X11 display:
ssh <username>#<ip> -X
aqtinstall is a good option: https://github.com/miurahr/aqtinstall
It's a simple command line tool to download and install any Qt version. It's a fork of my old qli-installer script.

Encounter "fatal error - NtCreateEvent(lock): 0xC0000077" when execute kinit in cygwin

I have mintty 1.2-beta1(x86_64-pc-cygwin) installed on my Windows 7 64 bit.
Then I installed krb5-workstation version 1.12.1-2 to cygwin using Cygwin Net Release Setup Program.
But when I execute kinit or klist in cygwin, I got an error:
$ kinit
1 [main] kinit 3912 C:\cygwin64\bin\kinit.exe: *** fatal error - NtCreateEvent(lock): 0xC0000077
Hangup
Restarting cygwin or restarting windows didn't work either.
Could anybody help?
I had the same error when starting xterm, which just appears to flash briefly, then exit producing an xterm.exe.stackdump file. If you give xterm the -hold option you will see the NtCreateEvent error. The root cause of my problem was interference from AVG anti virus, and adding c:\cygwin64\bin\xterm.exe to AVG's exception list made xterm work again.
I'm not sure if it helps, but I had the same error code when I was trying to install CPANminus in Cygwin 64-bit. However the installation worked fine in the 32-bit version. It's not a full solution, but maybe you can try the 32-bit version of Cygwin.
I wanted to run gdm3 on my Windows 7 desktop and ran into the same problems as you had. After some fiddeling, I got a working solution that I'm (very) happy with, so I wanted to share this with you. I did the following (you need to do this only once):
Start the Cygwin Terminal (on your Windows PC)
From the terminal, run xlaunch.exe and follow the dialogs (I ended up using XDMCP; a good article about configuring that can be found here)
Safe the resulting config file to your desktop
From now on, you can just click on the dekstop icon to launch the remote (gdm3) desktop.
AVG seems to be causing the exception including a rsync.exe.stackdump.
If you get on the server side:
rsync: safe_read failed to read 1 bytes [Receiver]: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(276) [Receiver=3.1.1]
or client side:
rsync.exe fatal error - NtCreateEvent(lock): 0xC0000058
try disabling AVG. If it works when disabled, I added the rsync.exe as an AVG program exception and rsync is fine again.

open Teamviewer on a Debian machine via PuTTY on a Windows machine

hope everyone is doing well.
Got an issue I would like to pick the great brains in this forum about.
So, I have many Debian machines I often remote into using Teamviewer and a Windows machine, which works out great; however Teamviewer crashes for what appears to be no apparent reason. When such happens, normally I will PuTTY into the suspect Debian machine from a Windows 7 machine and issue the shutdown -r now command. When the debian computer reboots, so does Teamviewer and the suspect Debian machine is now visible in the "My computers" list on my Windows machine.
My question is this, why cant I just type teamviewer from the command line while PuTTYing into the Debian machine and have Teamviewer reopen on the Debian machine, making it visible in "My computers?" When I execute teamviewer command from PuTTY command line, I see the verbose output of teamviewer opening, but the machine never becomes visible in "My computers."
Now, I know it is possible to start Teamviewer remotely and have it show up back in 'My computers" list. I can do it via NoMachine; I simply connect to the suspect Debian machine and double click on the Teamviewer desktop launcher. However, NoMachine is very heavy and quite frankly, i just don't like it. I also know I can execute teamviewer via command line while sitting in front of the suspect Debian machine. PuTTY would be so much faster.
I have also tried VNC as well as X sessions. In both cases, i can open Teamviewer and it shows up in "My computers," but when I close the VNC of X, Teamviewer also closes and removes itself from "My computers."
Can someone help me figure out a way to restart Teamviewer via PuTTY please? Is there a way to open a desktop launcher via PuTTYs command line? Or is there a way to tell Teamviewer to execute in the suspect Debian machines active desktop session via PuTTYs command line?
Thanks all

SSH tunnelling into arch box

I have a raspberry pi running arch linux connected to the TV and want to run commands on that screen by SSH'ing from my Ubuntu machine elsewhere.
I have tried running the command SSH -Y root# and starting xclock as a test. However I get the following error:
No protocol specified
Error: Can't open display: :0
I then tried running "export DISPLAY=:0" on the arch machine, but this doesn't solve the issue.
I have X running fine and can see it on the TV and I have edited the file /etc/ssh/ssh_config to allow X11 forwarding.
Anyone know what I am doing wrong?
Many thanks
The ArchLinux wiki has some good instructions on setting things up. I struggled for a while until I found them, but for me the key was to set up SSH forwarding within sshd_config (most distros seem to enable this by default, but Arch doesn't).
Once you've enabled X forwarding in SSHD, I also found it helpful to install the dummy video driver for Xorg ("pacman -S xf86-video-dummy"), which gets rid of irritating errors about missing the RANDR extension. This might not be necessary if you already have it running a real X server locally on the Pi - personally, I'm running mine completely headless.
I've found that I don't have to worry about setting up the DISPLAY variable, or xhost, when running with 'ssh -X' from an iMac. I'd expect Ubuntu to behave the same.
looks like an authentication problem. The answer used to be
xhost +
on the console of the X display. Might help.
You probably want to set
export DISPLAY=[IP_ADDRESS_OF_ARCH_BOX]:0
on your Ubuntu box, then when you run xclock from your Ubuntu box, it'll forward the screen to the Arch box.
