21.11-d89f18a1 fails after initial import with `nsenter: failed to parse pid: '-p'` about nixos-wsl HOT 9 CLOSED

The file you have contains the fix. That means there is another problem here
EDIT: I can reproduce the issue on my setup

from nixos-wsl.

The problem was introduced by a change from #64. The commit just before it was merged works just fine

from nixos-wsl.

Solves the problem for me. Thank you!

from nixos-wsl.

This nsenter: failed to parse pid: '-p' only occurs with the latest release 21.11-d89f18a1.

20.09-1c1f5649 works.

Seems like the An error occurred mounting one of your file systems. Please run 'dmesg' for more details. is a red herring and a separate issue.

from nixos-wsl.

Rebooting or terminating the instance after importing 'solves' the problem.

It looks like the installer leaves the system in a bad state.

The "An error occurred mounting one of your file systems. Please run 'dmesg' for more details." on first launch can be safely ignored. It should not happen after the installer has ran though. It happens because there is no /bin/mount present in the installer image.

You should not drop back to powershell after the installer finishes, instead a bash should open. There was an issue that caused the activation script to fail on the first start. I have pushed a fix for that issue and moved the release to that commit. The issue might be that you have a copy of the installer tarball that does not contain the fix. Can you give me the timestamp of the tarball you downloaded?

I have created a PR that should fix the issue. The CI should have built a tarball soon, so you can try if it works
