Title:
  Upgrade 16.04 LTS to 18.04 LTS failed

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

Bug description:
  System has been successfully running 16.04 for a long time. Although I
  have some PPAs configured and presumably this is breaking the upgrade,
  but there does not seem to be any way to determine which ones or how
  to go about making the upgrade possible.
