I have a problem with installing quickcheck from cabal on ubuntu 14.4 LTS. I have updated cabal, but when i try to install quickcheck an error comes up:

:~$ cabal install quickcheck

ghc: ghc no longer supports single-file style package databases (dist/package.conf.inplace) use 'ghc-pkg init' to create the database with the correct format.

cabal: Error: some packages failed to install:
QuickCheck-2.8.1 depends on random-1.1 which failed to install.

ExitFailure 1
random-1.1 failed during the building phase. The exception was:

This error occurs when you have a very old cabal binary compared to your version of ghc.

You could jump through the package manager routes, or you could use the linux binary download from https://www.haskell.org/cabal/download.html

That should suffice to get you off the ground...
