Also please be descriptive about the issue you're reporting, i.e: what you tried & what's the expected behaviour.

I updated my Nix-Flake with nix flake update and then tried to rebuild my system.

As a workaround, you can fix this by pinning auto-cpufreq to the latest version. IMO this is also safer than following the master branch.

auto-cpufreq = {
  url = "github:AdnanHodzic/auto-cpufreq/v2.4.0";
  inputs.nixpkgs.follows = "nixpkgs";
};

Fixed with the latest commit, sorry about that

[Svenum]

No problem. I use the master branch, because I love this project and will submit those kinds of issues. And help as much as I can. :)
