I am trying to update NixOS unstable on a notebook, but it has an issue and I need help with that.
# nix-channel --update unpacking channels... error: syntax error, unexpected $end, at /nix/store/0p8j75qgl3p98fvk46643awm0vy112i6-env-manifest.nix:1:1 error: program '/nix/store/0niikaryxswsig5zs5db1a41yr0pqzkl-nix-2.3.2/bin/nix-env' failed with exit code 1
/nix/store/0p8j75qgl3p98fvk46643awm0vy112i6-env-manifest.nix is empty.
I may have interrupted an update on this system some time ago. I do not remember well. Now I want to update it, but I do not know how to fix this issues.
Any clues on this is very well welcome.
