A new software development collaborative service for Ubuntu Linux is being launched today to give developers a consolidated arena to build code for Ubuntu on the desktop, server and for mobile applications.

In an announcement, Isle of Man-based Canonical Ltd., the development and commercial sponsor of Ubuntu, said the new Launchpad Personal Package Archive (PPA) service is being added to its existing Launchpad development Web site to allow groups to collaborate on packages, as well as allow individual developers to publish their own versions of open-source software.
