For some reason, after running nixos-rebuild, I get
error: getting attributes of path ‘/nix/store/4y965wrv3shgg2s1ca431qpbrsb4dbag-stdenv-linux’: No such file or directory
The path does indeed not exist in /nix/store, and there is also nother directory that contains stdenv-linux.
So it seems I am missing stdenv? And how can I restore it?
