Title:
  update-manager crashed with AttributeError in distUpgrade(): 'Package'
  object has no attribute '_list'

Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: update-manager

  I was trying to update my system, update-manager told me to do a
  partial upgrade. It was preparing the upgrade (step 1/4) and crashed
  then. When apt-get update && apt-get upgrading, apt-get had a problem
  with unmet dependencies from mainline kernel headers linux-
  headers-2.6.38-02063802, which I had installed for checking on another
  bug.
