[Bug 1573441] [NEW] upgrade to 16.04 fails

[god]

Public bug reported:

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.

** Affects: ubuntu-meta (Ubuntu)
     Importance: Undecided
