'''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. | |||

For temporary allowing unfree packages, you can use an environment variable: | |||
<syntaxhighlight lang="bash"> | |||
$ NIXPKGS_ALLOW_UNFREE=1 nix-shell -p vscode | |||
</syntaxhighlight> | </syntaxhighlight> | ||
Note for the new nix3-style commands, you need to pass <code>--impure</code> as well: | |||
== | <syntaxhighlight lang="bash"> | ||
$ NIXPKGS_ALLOW_UNFREE=1 nix run nixpkgs#vscode --impure | |||
</syntaxhighlight> | |||
== Hydra == | |||
[[Hydra]] does not build unfree software, and unfree software is unavailable in <code>cache.nixos.org</code>. | |||
