[Haskell-beginners] installing cabal 1.20 on linux mint debian edition (LMDE)

[Ovidiu Deac]

I'm trying to install a new version of cabal which supports sandboxes
(>=1.18). Note that the default version of cabal is 1.16.

Thanks for the pointers! I'll try installing from PPA in a few hours and
get back with an update
