Title:
  upgrade from 18.10 to 19.04 failed, backout didn't run

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

Bug description:
  Ran upgrade for 18.10 to 19.04. Towards the end of installing packages, there was an upgrade failed message saying it would run back-out. There was no mention of what specifically failed. The software updater then disappeared.
  After rebooting (perhaps a mistake) system is apparently working and lsb -rd and System says it's 19.04
