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?
