Either download from the cache:

nix-store -r /nix/store/478awaz17y6lijhk9xjxiz48whhlh9m4-gn-0-unstable-2026-01-07 \
  --option binary-caches 'https://cache.nixos.org/ https://nixpkgs-update-cache.nix-community.org/' \
  --option trusted-public-keys '
  nixpkgs-update-cache.nix-community.org-1:U8d6wiQecHUPJFSqHN9GSSmNkmdiFW7GW7WNAnHW0SM=
  cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
  '

(The nixpkgs-update cache is only trusted for this store-path realization.)
For the cached download to work, your user must be in the trusted-users list or you can use sudo since root is effectively trusted.

Or, build yourself:

nix-build -A gn https://github.com/r-ryantm/nixpkgs/archive/a1ef7ce8a89a409a3ed57470b434a32cbf810609.tar.gz

Or:

nix build github:r-ryantm/nixpkgs/a1ef7ce8a89a409a3ed57470b434a32cbf810609#gn

After you've downloaded or built it, look at the files and if there are any, run the binaries:

ls -la /nix/store/478awaz17y6lijhk9xjxiz48whhlh9m4-gn-0-unstable-2026-01-07
ls -la /nix/store/478awaz17y6lijhk9xjxiz48whhlh9m4-gn-0-unstable-2026-01-07/bin
