`lib` comes from the Nixpkgs used to instantiate Home Manager itself and cannot change within the module fixpoint. However, `pkgs` is configurable (via `nixpkgs.*` or `_module.args`) and may come from a different Nixpkgs instance from the one providing `lib`. Mismatches between Home Manager's release and the release of the `pkgs` instance are more common and also more likely to cause subtle issues. This change extends the release check to include `pkgs.lib.trivial.release` so that such mismatches can be detected and reported.

You are using
|
|
|
|
Home Manager version: ${hmRelease}
|
|
Nixpkgs version used to evaluate Home Manager: ${hmRelease}
|
|
Nixpkgs version used for packages (`pkgs`): ${pkgsRelease}
|
|
|
|
Using mismatched versions is likely to cause errors and unexpected
|
|
behavior. It is therefore highly recommended to use a release of Home
|
|
Manager that corresponds with your chosen release of Nixpkgs.

If you insist then you can disable this warning by adding
|
|
|
|
home.enableNixpkgsReleaseCheck = false;
