Title:
  upgrade to 16.04 fails

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

Bug description:
  The upgrade from 15.10 with all the updates installed fails:
  - when "sudo /usr/bin/python3 /usr/bin/do-release-upgrade --frontend=DistUpgradeViewGtk3" is executed it hangs forever:

  java version "1.7.0_95"
  OpenJDK Runtime Environment (IcedTea 2.6.4) (7u95-2.6.4-0ubuntu0.15.10.2)
  OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

  - when the same command is ran without sudo it downloads proper tar
  but fails with "no such file or directory" after trying to extract it:

  extracting 'xenial.tar.gz'
  Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

  Exactly the same behavior is observed than it's called indirectly from
  update-manager.
