Hello! Could you please provide more logs to help us better diagnose your issue?

To collect WSL logs, download and execute collect-wsl-logs.ps1 in an administrative powershell prompt:

Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/diagnostics/collect-wsl-logs.ps1" -OutFile collect-wsl-logs.ps1
Set-ExecutionPolicy Bypass -Scope Process -Force
.\collect-wsl-logs.ps1

The scipt will output the path of the log file once done.

Once completed please upload the output files to this Github issue.

Click here for more info on logging

Thank you!

anatawa12 · 2022-08-03T06:58:04Z

I've uploaded wsl logs.

benhillis · 2022-08-03T16:39:37Z

Thanks for the logs. The issue here is that sshd is not tied to a wsl.exe or wslhost.exe on the windows side (which handles interop requests). I have some thoughts on how to fix this, let me think about it a bit.

I am using fish-shell as our Ubuntu login shell.
config.fish contains the following:

Hello! Could you please provide more logs to help us better diagnose your issue?

To collect WSL logs, download and execute collect-wsl-logs.ps1 in an administrative powershell prompt:
Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/diagnostics/collect-wsl-logs.ps1" -OutFile collect-wsl-logs.ps1
Set-ExecutionPolicy Bypass -Scope Process -Force
.\collect-wsl-logs.ps1
The scipt will output the path of the log file once done.

Once completed please upload the output files to this Github issue.

G-Rath · 2023-04-09T22:46:07Z

As with others above, I've started getting this infrequently with some work I'm doing with Docker - previously I've been using docker for just local development which was mainly docker compose up powered which has never had this problem but this new work is related to deploying containers to ECS which involves docker build and docker push both of which are failing intermittently with this error.

My understanding is that the docker CLI on WSL is at some point talking to at least one exe managed by Docker for Windows, which could be why I'm hitting this (since everything else I'm doing is pure Ubuntu).

@OneBlue @benhillis I've not done any log collecting since it looks like there's a fair few already posted, but if either of you want to prioritize this I'm happy to be a guinea pig again to try and get any extra information you might need.

In my case, enabling the interop option in wsl.conf solved the problem.
It may not be a solution in every case, but I hope it helps someone.

I have no idea how this setting can solve the problem, because the value enable doesn't exist in the official documentation.

There is a value enabled and its default true.

MitchellBot · 2023-06-06T18:16:22Z

I get this on occasion and removing "credsStore": "desktop.exe" from ~/.docker/config.json fixes it.

sherif-elmetainy · 2023-06-18T09:39:37Z

I had the same problem and @MitchellBot's solution fixed it for me. Thanks a lot.

patricknelson · 2023-11-15T03:09:19Z

Bizarrely, I got this error too when running an exe from WSL2 (in my case, git-credential-wincred.exe) and the "solves all" quick fix of restarting WSL apparently worked for me as well. i.e. from a command prompt:

wsl --shutdown
wsl

Also worth a shot for anyone else. Interestingly, this was only an issue for me after applying a Docker Desktop upgrade as well. Very odd.

In my case, enabling the interop option in wsl.conf solved the problem.就我而言，在wsl.conf中启用互操作选项解决了问题。 It may not be a solution in every case, but I hope it helps someone.它可能不是每种情况下的解决方案，但我希望它对某人有所帮助。

Bizarrely, I got this error too when running an exe from WSL2 (in my case, git-credential-wincred.exe) and the "solves all" quick fix of restarting WSL apparently worked for me as well. i.e. from a command prompt:
wsl --shutdown
wsl

This worked for the similar issue that I had. The ERROR code was UtilAcceptVsock:250 instead of UtilAcceptVsock:246.

Still getting this error when trying to run a llamafile in WSL2. @benhillis quick mention to see if this is on the team's radar?

yeah man you get it. the problem about my wsl has been fix through this method
I have no idea how this setting can solve the problem, because the value enable doesn't exist in the official documentation.

There is a value enabled and its default true.

@bigfree is correct. Adding this to your config will cause a wsl: Unknown key 'interop.enable' error.

This is what worked for me.

To clarify, the error I receive is this:

<3>WSL (5984) ERROR: UtilAcceptVsock:248: accept4 failed 110

It is not resolved by enabling or disabling Interop as I have tried both methods.

I had the same issue and I remarked that most of WSL RAM was used
I stopped one vscode that was taking more than 4GB of memory !
I re-run vscode and this error disappeared

From microsoft/wslg#1308

I am running NixOS 24.05 and this issue happens to me when trying to use win32yank.exe from WSL.
