Title:
  error when tried to update to ubuntu 20.04 from 18.04.

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

Bug description:
  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.

  Got this message while attempting a upgrade from 18.04 to 20.04.
  I removed all PPA's except teams and brave from Softwate and Updates GUI
  Still getting same error
