[Bug 1445587] Re: Installer hangs after clicking "Restart Now"

[Launchpad Bug Tracker]

This bug was fixed in the package ubiquity - 2.21.23

---------------
ubiquity (2.21.23) vivid; urgency=medium

  * Stop running ubiquity.service as an oneshot service, as this blocks the
    initial boot transaction (including ureadahead etc.). Instead, manually
    start lightdm in the cases where we don't want ubiquity-dm.
  * GTK/KDE UI: GTK/KDE UI: Fix race between calling reboot/poweroff and the
    later stopping of the spawned X server by ubiquity-dm. We need to first
    shut down X orderly and then reboot/poweroff to get a proper transition to
    Plymouth.  This is a rather nasty hack; fixing this properly requires some
    more intrusive reeingeering. (LP: #1445587)
