Yeah, the problem is in lighthouse update, repeat that locally.

Tested it, nix-update doesn't work with CargoLock, so I will raise an issue in nix-update and suggest excluding lighthouse from periodic package updates.

The last v0.17.0 version of nix-update is working, so need to wait it for merging in nixpkgs-unstable.

But now lighthouse version is 4.0.2-rc.0, so nix-update will revert it to 4.0.1, so we need to disable lighthouse update anyway until they release a new stable version.

We could point directly to the flake for nix-update instead of relying on nixpkgs version.

Yeah, but nix-update is installed from nix-update-action github actions, which got that from nixpkgs input. Maybe it's a good idea to refactor nix-update-action to specify from where we should get our tools.

But anyway nix-update is already in a target branch :)
