Note this issue doesn't happen with wslu v4.1.3-1. But I'm reporting anyway in case it's a regression that needs to be fixed.

[felipecrs]

Also, I'm not sure why but the logs collector simply hangs and doesn't do anything.

wslu / wslvar is not maintained by Microsoft. I suggest following up with the owner of that project. Happy to help debug if we broke something, but I don't even know where to start here.

[felipecrs]

Well, my point was that WSL 2.4.4.0 broke it.

[justus-camp-microsoft]

We don't maintain the tool and don't make any guarantees about not breaking it between releases. I would recommend opening an issue against the tool's repo.

[felipecrs]

Alright. Since it's not broken in the tool's latest version, I will not open an issue there.

For posteriority, since even the newest Ubuntu on WSL still packages wslu v3, the solution is to install their PPA to have wslu upgraded to v4.
