Either **download from the cache**:
```
nix-store -r /nix/store/g9qi2zrsxpvhi8gm24ndsh7vmbkqf0nr-cpuinfo-0-unstable-2026-07-01 \
--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 cpuinfo https://github.com/r-ryantm/nixpkgs/archive/cb482adb9efafdbe07f42082fa5697bab9ea2d11.tar.gz
```
Or:
```
nix build github:r-ryantm/nixpkgs/cb482adb9efafdbe07f42082fa5697bab9ea2d11#cpuinfo
```
After you've downloaded or built it, look at the files and if there are any, run the binaries:
```
ls -la /nix/store/g9qi2zrsxpvhi8gm24ndsh7vmbkqf0nr-cpuinfo-0-unstable-2026-07-01
ls -la /nix/store/g9qi2zrsxpvhi8gm24ndsh7vmbkqf0nr-cpuinfo-0-unstable-2026-07-01/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.
