Title:
  do-release-upgrade of 18.04 LTS -> 18.10 failed due to gconf2

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

Bug description:
  I was upgrading my laptop from 18.04 LTS to 18.10 with

      apt update
      apt upgrade
      do-release-upgrade

  and it failed, due to

       dpkg: dependency problems prevent processing triggers for gconf2:
        gconf2 priklauso nuo psmisc; tačiau:
         Paketas psmisc dar nekonfigūruotas.

       dpkg: klaida, apdorojant paketą gconf2 (--configure):
        dependency problems - leaving triggers unprocessed

  in a loop until dpkg gave up.

  Could this be another instance of bug 1780996?

  (I'm not sure why I even had gconf2 installed.  No apps depend on it.
  Might be some build dependency pulled it in a while ago -- I was
  building gvim from source on this machine since before it was ported
  to GTK+ 3.)
