• Lix is preferred: https://lix.systems/install/
  • Works with NixOS and Home-Manager as it's a drop-in replacement.

By default if installed (at least when installing Lix), nixpkgs points to the unstable channel. To change this, open the file /etc/nix/nix.conf and edit the line starting with extra-nix-path = to this (might need a more up-to-date path)

extra-nix-path = nixpkgs=flake:nixpkgs/nixos-24.05
