Our nix flake self-check CI started failing a few days ago due to nixpkgs being more than 30 days old. This is easily fixed by running nix flake update as was done to resolve the issue (here). We should automate this and proactively create PRs to prevent CI from breaking again. See the "What to do" section on this recent failed run for instructions on how to set this up. In short, we should use the update-flake-lock GitHub action.
