Build cache populated?

[berquist]

I'm trying to use the latest version of the flake and I think the build cache is not being populated, since it tries to build the Psi4 stack (for example) from source. I checked CI and found https://github.com/Nix-QChem/NixOS-QChem/actions/runs/11328882309/job/31503175530?pr=566#step:15:3. Can someone else confirm this?

We do not use Github actions to populate the cache, but a locally running Hydra (the default Github runners do not have enough compute power).
The latest flake builds are available via cachix. Did you add the cachix public key to your config as a trusted public key?

I check if we can add this key to the flake.
