At some point, I borked my nix channels. When I run
nix-channel --list I get two entries:
" " nixos https://nixos.org/channels/nixos-unstable
I can’t remove the blank entry with
nix-channel --remove " ". I get:
warning: selector ' ' matched no installed derivations
I can no longer run
nixos-rebuild without explicitly specifying a NIX_PATH. I’m guessing that this erroneous channel is the reason why.
Does anyone know how I can clean this up?
