Cabal install package fails weirdly

Question

I access internet through a proxy and have appropriately set up the environment variables. The problem is that whenever I am trying to install any package through cabal, it fails with a

connect: does not exist (Connection Refused) error.

But if I run cabal update -v3, it successfully makes the connection and retrieves the update information.

$ cabal --version   
cabal-install version 1.20.0.2
using version 1.20.0.1 of the Cabal library

Edit: I'm running Ubuntu 14.04.

@VivekRai Does this happen to you sometimes or everytime ? I have experienced this problem occasionally under a proxy. — Sibi, Jul 18 '14 at 16:42
@Sibi As far as I know, it has been happening since two days. I would change the proxy and try again. — Vivek Rai, Jul 18 '14 at 18:48

Okay. The problem is solved by using -E with sudo command.

sudo -E cabal install <package>

Although, I don't understand why cabal update could work but not cabal install.
