Title:
  upgrade from 14.04 to 16.04 fails with: ca-certificates
  20170717~16.04.1 failed to install/upgrade: triggers looping,
  abandoned

Status in dpkg package in Ubuntu:
  Confirmed

Bug description:
  Test Case:
  1. Install Ubuntu server 14.04.5 + all the updates
  2. Install ca-certificates-java and man-db
  3. Reboot
  4. Upgrade to 16.04 LTS with do-release-upgrade and proceed with the upgrade

  Actual Result
  Upgrade fails with
  Removing ca-certificates-java (20130815ubuntu1) ...
  Removing openjdk-7-jre-headless:amd64 (7u151-2.6.11-2ubuntu0.14.04.1) ...
  dpkg: cycle found while processing triggers:
   chain of packages whose triggers are or may be responsible:
    man-db -> ca-certificates
   packages' pending triggers which are or may be unresolvable:
    ca-certificates: update-ca-certificates
    man-db: /usr/share/man
  dpkg: error processing package ca-certificates (--remove):
   triggers looping, abandoned

  I have no further information to give at this time except to say that there were several errors during the upgrade process from 14.04.
