[Bug 1985871] Re: Could not calculate the upgrade

[Nick Rosbrook]

Please see https://help.ubuntu.com/community/EOLUpgrades for information
on how to upgrade from an EOL release. For starters, you will need to
update your /etc/apt/sources.list to use old-releases.ubuntu.com instead
of sa.archive.ubuntu.com.

After that, please try the upgrade again.

Title:
  Could not calculate the upgrade

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

Bug description:
  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'.
