• What does running nix-instantiate --eval --strict -A cabal2nix.meta.outputsToInstall '<nixpkgs>' yield?
• Find out what revision your nixpkgs channel is using, e.g. via nix-instantiate --eval --strict '<nixpkgs>' -A lib.version.

This is a weird error which sometimes happens with no known definite cause

Maybe -vvvvvvvv with nix-env would show something useful.
