You could use stack instead of cabal. The most recent nightly stack
snapshots use GHC 8.4.3. Stack has a lot[1] of advantages. One of them is
that you can use a bunch of different versions of GHC at the same time.
Whereas Cabal keeps a global collection of Haskell software, Stack keeps a
bunch of different local ones, while cleverly avoiding wasting memory like
you might expect that to imply. If you have a project that needs old stuff
that's incompatible with new stuff, you're SOL with Cabal but it's no
problem in Stack.

While installing ghc-8.4.3-i386-deb8-linux.tar.xz at Debian8 went smoothly, can't se how to install ghc-8.4.3 at Ubuntu resp. Xubuntu:
in dir ghc-8.4.3/
./configure checking for gfind... no checking for find... /usr/bin/find checking for sort... /usr/bin/sort checking for GHC Git commit id... given 51abb1c88b53e2989a2a8c2939ac4abc04bef194 checking for ghc... /usr/bin/ghc checking version of ghc... 7.10.3 configure: error: GHC version 8.0 or later is required to compile GHC.
Did cabal update
and tried haskell-platform for ubuntu https://www.haskell.org/platform/linux.html#linux-ubuntu
which seems broken
Tried Haskell-platform from source:
./platform.sh *** *** Building hptool *** cabal: unrecognised command: new-build (try --help)
Any help?
Cheers, Andreas
