Hi, I have tried using cabal-install-2.4.0.0 but it installs incorrectly. The error seems to have been resolved with issue https://github.com/haskell/cabal/issues/5516 it would be nice to get this fix and get the newer version of cabal that fixes a lot of the v2 problems. The latest stable release seems to be v3.2.0.0 https://github.com/haskell/cabal/releases.
