1.18 and 1.20 patch releases done

[Miëtek Bak]

I’m not sure if I understand the problem.  I believe bootstrap.sh should be expected to be run only on a bare system with nothing but GHC installed.  If the user is already able to install Cabal packages, i.e. has some version cabal-install, they should be using that, not bootstrap.sh.  Does this assumption simplify the problem you’re seeing?

In fact I don't know if I can get bootstrap.sh working at all. Without actually using cabal-install to do the dependency/flag resolution and make sure we build using a consistent set of packages we end up in problems like these:
