Probably related to NixOS/nix#9052

What should I do then?

[Kranzes]

Not use 2.18. For about a week now unstable has reverted nixUnstable to be 2.17.

[mobsenpai]

I tried changing this line https://github.com/MobSenpai/dotfiles/blob/f9d579a0cdca6ed6eec35af9e5faca292e9e9c76/hosts/shared/nix.nix#L44 to pkgs.nixVersions.nix_2_17
but it didn't work

Not use 2.18. For about a week now unstable has reverted nixUnstable to be 2.17.

[Kranzes]

You daemon also has to use 2.17, did you try rebooting?

[mobsenpai]

I think I somehow broke my nixos install. Reinstalling fixes it.
