Installation failed

Fri May 31 08:46:56 UTC 2019

Sorry, I wrote non-sense, the command is

cabal user-config update

--

cabal-install-3.0.0.0 is the latest (and in fact non-released) version 
you can have. Your last (failed) attempt actually wanted to install 
cabal-install-2.4.1.0!

Reinstalling cabal-install (from Hackage) via cabal-install is currently 
not well exercised codepath. People usually install cabal from either 
Herbert's PPA, via ghcup or chocolatey package managers. So even I don't 
see reason installing cabal-install via cabal-install shouldn't work, I 
don't recommend it.

The zlib.h failure is related to no zlib library - development parts 
installed. On Ubuntu the headers can be installed by "apt-get install 
zlib1g-dev". Unfortunately I have no experience with WSL, if that's as 
easy there.
