error: attribute 'overrideScope'' missing

When rebuilding my system on the latest nixpkgs-unstable, I get the following error:

       Did you mean overrideScope?

I think the root cause is just that the flake.lock needs updating to pick up the latest changes in crane. It looks like there is a PR to update the lockfile in progress #408, but the build is broken.

For anybody who wants a temporary fix you can override crane to the specific commit where they started using overrideScope by doing nix flake update --override-input lanzaboote/crane github:ipetkov/crane/f2926e34a1599837f3256c701739529d772e36e7 since it doesn't seem like it breaks with lanzaboote
