Title:
  14.04 LTS -> 16.04 LTS upgrade errors with cups/insserv

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

Bug description:
  Upgraded a ~~precise~~ trusty server to xenial with sudo do-release-
  upgrade.  Got a bunch of errors while upgrading cups because insserv
  was deeply unhappy about init script dependencies (loops loops
  everywhere).

  I'm hoping ubuntu-bug is smart enough to attach the relevant /var/log
  /dist-upgrade/ log files.
