Bug description:
  Unable to upgrade Ubuntu 14.04 to 15.04.

  /var/log/dist-upgrade/apt.log lists some major packages (like
  libstdc++6) which have dependencies which can't be satisifed, and
  trying trying to resolve it by deinstalling I get warnings about this
  will seriously damage my system if I deinstall.

  But with them installed I can't seem to upgrade ubuntu.
