It’s done: Sugar packages for Ubuntu Jaunty are no longer maintained in Git at Alioth. Read more here
Usually we maintain Sugar packages in Debian’s Git services at Alioth. Ideally, every Ubuntu SugarTeam member is also a Debian OLPC maintainer on Alioth, who have the rights to push Debian/Ubuntu-spesific fixes upstream. When we are close to a freeze or are unable to work with upstream (Debian) to meet our 6-month-release-cycle-deadline, we are forced to diverge from their repositories. Keep in mind, however, that we have the full expectation to merge at the soonest juncture.
