[Bug 2134608] Re: Unable to update ubuntu

[Eduardo Barretto]

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

Title:
  Unable to update ubuntu

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  This is what I got while upgrading my system: Could not calculate the
  upgrade

  An unresolvable problem occurred while calculating the upgrade.   This
  was likely caused by:  * Unofficial software packages not provided by
  Ubuntu  Please use the tool 'ppa-purge' from the ppa-purge  package to
  remove software from a Launchpad PPA and  try the upgrade again.   If
  none of this applies, then please report this bug using the  command
  'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

  If  you want to investigate this yourself the log files in
  '/var/log/dist-upgrade' will contain details about the upgrade.
  Specifically, look at 'main.log' and 'apt.log'.     Restoring original
  system state   Aborting
