Title:
  Upgrade fails silently with missing directory permissions

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

Bug description:
  Binary package hint: update-manager

  When trying to upgrade to Natty (11.04), pressing the "Upgrade" button
  in the release notes dialog silently aborts the upgrade and returns to
  the update-manager main window. This is due to restrictive permissions
  (0700) on the APT archives directory (a remnant of using apt-offline,
  if I remember correctly).

  On the console, the following error message can be seen:

  acolomb at pythagoras:~$ update-manager 
  Traceback (most recent call last):
    File "/usr/lib/python2.6/dist-packages/UpdateManager/UpdateManager.py", line 962, in on_button_dist_upgrade_clicked

      result = fetcher.run()
