This may be caused by some cabal.project lying around (e.g., in the directory you are in when you are installing, but also in any parent directory) or by .ghc.environment.arch-os-version files lying around

I don't have a cabal.project or .ghc.environment.arch-os-version lying around. However, I've found ~/.ghc/x86_64-linux-8.8.4/environments/default, which contains this:
GHC 8.8.4 depends on directory 1.3.6.0, therefore the GHC API package, ghc, does too as mentioned in the original error message: [__1] rejecting: ghc-8.8.4/installed-8.8... (conflict: directory==1.3.7.1, ghc => directory==1.3.6.0/installed-1.3...) and can be verified at: https://gitlab.haskell.org/ghc/ghc/-/wikis/commentary/libraries/version-hist... However, you have got an environment file that requires ghc-8.8.4 and directory-1.3.7.1 at the same time. Something's funny about that because it's impossible to satisfy and I'm not sure how it could have happened in the first place. Perhaps some cabal expert can weigh in. Tom
