Unfree software, sometimes called nonfree software, is software that cannot be freely modified or distributed. Nixpkgs provides packages for unfree software, but additional configuration is required before they can be used.
Using unfree packages
Per-package (preferred)
This method works for both NixOS system level configuration and Home Manager:
/etc/nixos/configuration.nix
{
nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"vscode"
];
}
For all packages
This method works for both NixOS system level configuration and Home Manager:
/etc/nixos/configuration.nix
{
nixpkgs.config.allowUnfree = true;
}
Command line
You won't be able to install or search for an unfree package as a user unless you explicitly enable it:
~/.config/nixpkgs/config.nix
{
allowUnfree = true;
}
Temporarily allowing
For temporary allowing unfree packages, you can use an environment variable:
$ NIXPKGS_ALLOW_UNFREE=1 nix-shell -p vscode
Note for the new nix3-style commands, you need to pass --impure as well:
$ NIXPKGS_ALLOW_UNFREE=1 nix run nixpkgs#vscode --impure
Hydra
Hydra does not build unfree software, and unfree software is unavailable in cache.nixos.org.
