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 On Thu, May 29, 2014 at 9:22 AM, Christopher Allen wrote:

Also were you trying to build it in a sandbox? You shouldn't be installing things willy-nilly outside of a sandbox[3].

I'm trying to install cabal 1.20 like this:

I installed ghc and ghc-prof from apt repository so I got the following: ii ghc 7.6.3-5 amd64 The Glasgow Haskell Compilation s ii ghc-prof 7.6.3-5 amd64 Profiling libraries for the Glasg

Then I git cloned cabal and checked out Cabal-v1.20.0.0

Then I ran bootstrap.sh in cabal-install dir and I get the following error:

Install (any) cabal package in Ubuntu (with synaptic), and than run

cabal update cabal install cabal

After that new cabal will be in your .cabal/bin directory (which should be on your path), and available to you only.

Cabal is just another package that can be installed. Current version is 1.20

That should be:

$ cabal install cabal-install

Cabal is a library, and cabal-install is the executable.

Eventually I fixed the problem by using the Trusty apt repository and then let cabal update itself. Thanks! On Thu, May 29, 2014 at 11:06 PM, Dan Serban wrote:
