Bug Description

Binary package hint: update-manager

Attached is a log from a intrepid->jaunty upgrade. It was performed on release day where the de.archive.ubuntu.com server was pretty overloaded. It seems that because of that the upgrade had no packages to upgrade.

There are two issues here:
- the overloaded server returned bogus apt-get update results for the jaunty repository
- the upgrader did not detected this error and continued to perform a intrepid->jaunty upgrade

The only packages upgraded were:
firefox
3.0.9+nobinonly-0ubuntu0.8.10.1
3.0.9+nobinonly-0ubuntu0.9.04.1

that was in security.ubuntu.com jaunty-security at this time.

I will attach the log from the upgrade.

One theory is that the server returned 304 (not modfied) for all requests. This might in theory result in a empty /var/lib/apt/lists and would explain the behavior that no upgrades (other than security.ubuntu.com) could be found.

  * UpdateManager/UpdateManager.py:
    - show origin field for other updates (like PPAs) to make it
