  • 86_64-linux
  • GHC 9.4.8
  • Haskell.nix commit 12913ad

My configuration flake contains:
nix.settings.substituters = [ "https://cache.iog.io" ];
nix.settings.trusted-public-keys = [ "hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ=" ];

The Haskell flake:
nixConfig = {
extra-substituters = ["https://cache.iog.io"];
extra-trusted-public-keys = ["hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ="];
allow-import-from-derivation = "true";
};
}

And yet when I run "nix develop" it goes through the lengthy process of building ghc-9.4.8 from scratch. The binary cache doesn't seem to be getting hit.
