The auto-update exploded because Ubuntu pushed out an update to at(1), which killed atd(8), which in turn killed the update process. On machines which have not rebooted, atd is dead and no updates will occur. On machines which have rebooted, atd will attempt to continue, but dpkg --configure will fail because it doesn't like the state of the at package, and insists on reinstallation.
We're looking at our options at this point.
