Title:
  unattended-upgrades hangs system on shutdown

Status in Unattended upgrades:
  New
Status in “unattended-upgrades” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: unattended-upgrades

  I am running Kubuntu-Netbook, based on Karmic I believe, my problem
  relates to shutting down the netbook.

  version appears as: Installed 0.52ubuntu1

  I'd expect the machine to shutdown, reboot when requested.

  Instead it appears to shut down nicely until I see

  *Shutting down ALSA               [ OK ]
  Checking for running unattended-upgrades:* Asking all remaining processess to terminate    _

  and it will just sit there, forever.

  The unattended-upgrades script in /etc/init.d has been run on a
  seperate machine by hand and appears to hang on that machine also.

  My bug reporting is not much up to scratch, so I hope I've covered it.
