This was caused by an incorrect version number used for a python-ldb
security update (see bug 2009895), and has since been resolved.

Title:
  Could not calculate the upgrade  An unresolvable problem occurred
  while calculating the upgrade.

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

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'.

  I don't know how to proceed
