Ok, so here's the weird thing... I don't have any "cabal-install" package
in my PPA; I do however have a "cabal-install-3.0" package (i.e. the 3.0 is
part of the version number, because I supply one package per major version
of cabal).

So I'd expect you'd find something like

ii  cabal-install-3.0
 3.0+git20190317.1.b3d6d0b-6~16.04            amd64        Command-line
interface for Cabal and Hackage

if you executed `dpkg -l | grep cabal-install`... (i.e. the "version" is
that monstrous "3.0+git20190317.1.b3d6d0b-6~16.04"  thing)

Interesting. I'll investigate... maybe I'll be able to discontinue the WSL
ppa at last... :-)
