Updating Kicad in Ubuntu 14.04

I’m having some issues updating Kicad as well. My current version is 2015-05-01 BZR4839. In Software Sources under Ubuntu Software Center the js-reynaud ppa is disabled. The box “disabled on upgrade to trusty” is ticked. Should this be unticked? Is there any other way to update Kicad?? Kicad used to update almost daily at one time.

In Software Sources under Ubuntu Software Center the js-reynaud ppa is disabled.

So, enable it?
