Package ‘util-linux-2.28’ in ‘/home/user/nixpkgs/pkgs/os-specific/linux/util-linux/default.nix:68’ is not supported on ‘x86_64-darwin’, refusing to evaluate.
a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build` or any other Nix command you can add
  { allowBroken = true; }
to ~/.nixpkgs/config.nix.
