[Bug 934499] Re: Unable to upgrade from 11.04 to 11.10

[RedSingularity]

If you are able to install software, that means there should no longer be any lock.  Update-manager should run fine now.  How is it?

  Unable to upgrade from 11.04 to 11.10

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

Bug description:
  === Problem ===
  Unable to upgrade from Ubuntu 11.04 (Natty Narwhal) to Ubuntu 11.10 (Oneiric Ocelot) using update-manager --dist-upgrade tool. 

  
  === Repro ===
  1. ALT+F2
  2. update-manager --dist-upgrade

  === Actual result ===
  An error message occurs while trying to upgrade to 11.10
  """
  Unable to get exclusive lock

  This usually means that another package management application (like apt-get or aptitude) already running. Please close that application first.
  """

  Neither apt nor synaptic nor dpkg processes is running.
  Manual clean of /var/lib/dpkg/lock doesn't help to fix this.
  No broken packages are present in system.
