On main it is expected that you update to 23.11, otherwise use https://github.com/nix-community/NixOS-WSL/releases/tag/23.5.5.2

[roosmaa]

I'm sorry but what you said makes zero sense to me as a Nix newbie. I followed the instructions in the readme, they ended in error. Thus the bug report as either the instructions are wrong or something is broken.

I'll just drop it here in case it helps anyone just starting with Nix, here's how one can update the channel to 23.11:

sudo nix-channel --add  https://nixos.org/channels/nixos-23.11 nixos
sudo nix-channel --update
sudo nixos-rebuild switch

[MrScriptX]

It should be mentioned in the README

[SuperSandro2000]

did so in #357

[roosmaa]

@SuperSandro2000 I think the problem is also that the latest tag (23.5.5.2, the file I downloaded), points to the main branch instead of the 23.5.5.2 itself. Thus the breakage and confusing.

[SuperSandro2000]

hmmm, maybe we can fix this when we offer proper channels but until then main is for nixos-unstable :)
