Either download from the cache:

nix-store -r /nix/store/yacnwcd3k0f9dbpdza0apghzcm52xdsm-cpuinfo-0-unstable-2026-04-30 \
  --option binary-caches 'https://cache.nixos.org/ https://nixpkgs-update-cache.nix-community.org/' \
  --option trusted-public-keys '

(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 cpuinfo https://github.com/r-ryantm/nixpkgs/archive/ba21cfd1a766c8d0c482c33a07bd6dd119cfab94.tar.gz

Or:

nix build github:r-ryantm/nixpkgs/ba21cfd1a766c8d0c482c33a07bd6dd119cfab94#cpuinfo

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

ls -la /nix/store/yacnwcd3k0f9dbpdza0apghzcm52xdsm-cpuinfo-0-unstable-2026-04-30
ls -la /nix/store/yacnwcd3k0f9dbpdza0apghzcm52xdsm-cpuinfo-0-unstable-2026-04-30/bin

Pre-merge build results

We have automatically built all packages that will get rebuilt due to
this change.

This gives evidence on whether the upgrade will break dependent packages.
Note sometimes packages show up as failed to build independent of the
change, simply because they are already broken on the target branch.
