PS: How does one go about downgrading Cabal and cabal-install? If we wanted to check whether cabal is the problem, how?

You can force the Cabal lib version to use (in case you have multiple versions installed) with 'install --cabal-lib-version'. To downgrade cabal-install itself to some older version you need to compile and install that version.
