  Cannot upgrade to Ubuntu 15.10 (Installer Exits)

  Incomplete

Bug description:
  Currently running Ubuntu 15.04. I run the Software Updater and it says
  "system up to date, but there is an update to 15.10". I click Upgrade,
  and nothing happens. I have looked in the various logs suggested by
  other posts (syslog, dpkg.log, /varlog/apt/*.log, etc - but I cannot
  find any error messages. How can I troubleshoot this?
