Hi everyone I am beginner of nixos
I can’t install unfree package
in .config/nixpkgs/config.nix
{
allowUnfree = true;
}
and in configuration.nix
nixpkgs.config.allowUnfree = true;
what shoud I do?
Sorry for my poor English
Can you share what command you’re running that fails to install an unfree package, and what error message you’re getting?
thank you for your reply
$ sudo nixos-rebuild switch

error: Package ‘zoom-6.0.2.4680’ in /nix/store/4vfim1qajqp056drin5dpfibbqkrlm88-nixos-24.05/nixos/pkgs/applications/networking/instant-messengers/zoom-us/default.nix:195 has an unfree license (‘unfree’), refusing to evaluate.
a) To temporarily allow unfree packages, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_UNFREE=1
Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
then pass `--impure` in order to allow use of environment variables.
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
Alternatively you can configure a predicate to allow specific packages:
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"zoom"
];
}
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.
This should have been sufficient, if nixpkgs.pkgs isn’t set. Can you share your full configuration.nix?

By default, home-manager does not use the same nixpkgs instance as the system. So when you change the nixpkgs configuration of your system, it doesn’t affect home-manager.
You can either make home-manager configure its nixpkgs to allow unfree packages, or you can make them share the configuration. I prefer the latter. To do that, add this to your home-manager module config:
home-manager = {
useGlobalPkgs = true;
users.tilt = import ./home.nix;
};
