'https://cache.iog.io' is not signed by any of the keys in 'trusted-public-keys

[spirals2]

I run into issues when running nix develop where it seems a lot nix paths have issues like: warning: the substitute for '/nix/store/9gby2vh0xbz435pdx5scd0rlsd03y1im-czipwith-1.0.1.4-1.cabal' from 'https://cache.iog.io' is not signed by any of the keys in 'trusted-public-keys'

Similar issues seem to be reported here: https://discourse.nixos.org/t/whats-the-trusted-public-key-for-cache-iog-io/23806

In my nix conf I have:

substituters = https://cache.nixos.org https://nix-tools.cachix.org https://cache.nixos.org/ https://cache.iog.io https://all-hies.cachix.org https://haskell-language-server.cachix.org https://public-plutonomicon.cachix.org https://iohk.cachix.org

you should use hydra.iohk.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= instead of cache.iog.io:f/Ea+s+dFdN+3Y/G+FDgSq+a5NEWhJGzdjvKNGv0/EQ= even though https://cache.iog.io is used in the substituters attribute. See https://input-output-hk.github.io/haskell.nix/tutorials/getting-started#setting-up-the-binary-cache.

Also just to note that you have https://cache.nixos.org twice listed in your substituters you might want to remove duplicates.
