nsenter: failed to parse pid: '-p'

[Panke]

Bug description

I installed it but I cannot start it, because `nsenter: failed to parse pid: '-p'.

To Reproduce

1. Get the installer and follow readme instructions (see terminal output below)

Include relevant console logs

Duplicate of #67

Please try the -fixed installer.

[Panke]

Ah sorry, I only looked at the open bugs.

[sielicki]

@nzbr is it possible to delete the old tarball on the release page?

[nzbr]

I did (again). The CI re-uploads it every time I change the release text

[nzbr]

I can't force-push the tag, unfortunately. It stopped working a while ago. @Mic92 ist that on purpose? Or is something broken on my end?

[Panke]

Works with the newer release!

[RivenSkaye]

Commenting here because this is resurfacing for me when installing the latest release. The entire unpacking step works perfectly fine, but then it just sits there, claiming to start systemd but never actually carrying on. SIGKILL is required to continue (I let it sit for well over 20 mins). Afterwards, any attempt to start wsl -d NixOS results in the same error.

At this point, ctrl+C is the only way to continue. The shell hangs on this, presumably because of the following:

> wsl -d NixOS
nsenter: failed to parse pid: '-p'

In the meantime I'll try installing the previous (-fixed) release and upgrading from there to see if it helps

[nzbr]

@RivenSkaye Did you manage to get it to work? If not, can you try the latest build? (the installer tarball is inside the "installer" artifact, so you'll need to unpack that first)

[dliberalesso]

@RivenSkaye You can install direclty via the tarball available in the latest build using the command wsl --import NixOS .\NixOS\ nixos-wsl-x86_64-linux.tar.gz --version 2.

[nzbr]

@dliberalesso The link I shared doesn't go to the latest release, but the latest CI run of the main branch, which is a few commits ahead and contains a full rewrite of syschdemd (the systemd wrapper script)

[dliberalesso]

@nzbr In that case, I'll try it too. Thanks!

[jamesreprise]

I also had the exact same issue as @RivenSkaye and @nzbr's fix worked perfectly (thank you!) It might be worth re-opening this issue so that it's visible to anyone else having the same problem without removing issue:open.

[nzbr]

I have left the issue closed (as it seems to be fixed on main), but pinned it so that anyone experiencing that problem can find it on top of the issue list
