WSL2 with Ubuntu not starting anymore - Blinking cursor

[gennaris]

Windows Version

Microsoft Windows [Versione 10.0.22631.3958]

WSL Version

2.2.4.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

No response

Distro Version

Ubuntu (Windows Store)

Other Software

Docker Desktop 4.33.1

Repro Steps

WSL2, which I use with Ubuntu, suddenly stopped working without any apparent reason, only showing a blinking cursor when launched.

I suspect that the issue might be somehow related to Docker Desktop, as the problem started after I updated it to the latest version.

When I launch Docker Desktop, I get the following error:

bootstrapping in the main distro: listing WSL distros: running WSL command wsl.exe C:\Windows\System32\wsl.exe -l -v --all: context deadline exceeded

Running wsl -v returns:

WSL Version: 2.2.4.0
Kernel Version: 5.15.153.1-2
WSLg Version: 1.0.61
MSRDC Version: 1.2.5326
Direct3D Version: 1.611.1-81528511
DXCore Version: 10.0.26091.1-240325-1447.ge-release
Windows Version: 10.0.22631.3958

However, wsl -l -v hangs indefinitely.

I have already tried the following steps without success:

Uninstalling/reinstalling "Ubuntu" from the Windows Store
Completely uninstalling/reinstalling Docker Desktop
Disabling/re-enabling WSL and Virtual Machine Platform from the Windows Features.
I am attaching the logs generated by the diagnostic script for your reference.

Expected Behavior

I expect wsl.exe running correctly, I have used it for over a year without any problems

Actual Behavior

WSL shows a blinking cursor when launched

You can try to see if the "Window Update Health Tools" is running in the background.

Thank you @gennaris. Looks like WSL is stuck. Can you capture share process dump of when WSL is in that state ?

I have the same problem since this morning. Suddenly nothing is working anymore. I have multiple WSL instances of Ubuntu installed. Neither of them is starting since today. I have the same versions as in the original post:

WSL-Version: 2.2.4.0
Kernelversion: 5.15.153.1-2
WSLg-Version: 1.0.61
MSRDC-Version: 1.2.5326
Direct3D-Version: 1.611.1-81528511
DXCore-Version: 10.0.26091.1-240325-1447.ge-release
Windows-Version: 10.0.22631.3958

Most of the instances have the same behavior like @gennaris described. But one instance (my oldest one) shows after some cursor blinking (1 or 2 minutes) this error (sorry for the german language 😀):

Der Netzwerkname wurde nicht gefunden.
Error code: Wsl/0x80070043

[Verarbeitung des Prozesses mit Code 4294967295 (0xffffffff) beendet]
Sie können dieses Terminal jetzt mit STRG+D schließen oder zum Neustart die EINGABETASTE drücken.

So maybe there is something going on with the network? I also cannot access my WSL file systems in the windows explorer. It simply shows nothing and the round waiting indicator in the Linux Tab on top keeps spinning:

Commands like wsl --list are not working and hang infinitely. (Only command to work seems wsl --version)
Yesterday I installed the newest Windows update. Maybe this introduced some kind of bug?

I have just checked again for Windows updates. And there really was a new one. This seemed to fix the problem. After updating everything is working again. This are the version numbers now:

WSL-Version: 2.2.4.0
Kernelversion: 5.15.153.1-2
WSLg-Version: 1.0.61
MSRDC-Version: 1.2.5326
Direct3D-Version: 1.611.1-81528511
DXCore-Version: 10.0.26091.1-240325-1447.ge-release
Windows-Version: 10.0.22631.4037

The only part that changed is the windows version (from 10.0.22631.3958 to 10.0.22631.4037)

So @gennaris maybe you should check for available Windows updates

@fscheuMoba I downloaded and applied the latest mentioned Windows Update, and after a reboot, I was able to successfully launch WSL and use the Ubuntu CLI.
However, as soon as I launched Docker Desktop, the blocking condition described at the beginning of the issue reoccurred and WSL is getting stuck until a new reboot.
I also tried downgrading Docker Desktop again from version 4.33.1 to version 4.29 (which was previously working), but I still have the same problem.

@OneBlue How can i provide the process share dump?

I tried :

Taskmgr.exe /dump {pid_of_one_of_the_wsl.exe_processes} /Full /file "C:\dump.dmp"

but nothing got written on disk.

I've had a chance to do some more testing these days (uninstalling/reinstalling) but I'm not getting to the bottom of it.

I managed to get the situation where WSL works correctly with any distribution after reboot, but as soon as I launch “Docker Desktop” , WSL crashes and enters the situation described at the beginning of the ticket - At that point a reboot is needed to make WSL working again.
