Restart after installation logs out rather than rebooting

[Erick Brunzell]

Just testing Ubuntu 20150421.1 amd64 and after installing I clicked on Restart and rather than completing the reboot process I landed at the login screen. I was unable to log back into the live DE or reboot using the restart option from the login screen so I did a hard reset. The installation had been started from the live DE. Hopefully the logs attached will be helpful.

This was fixed in ubiquity 2.21.25 vivid:

ubiquity (2.21.25) vivid; urgency=medium

  * GTK/KDE UI: Don't apply the reboot/poweroff race hack when running under
    an actual display-manager, i. e. go back to what we always did there. This
    fixes restarting the greeter after clicking "restart" at the end of
    installation. lightdm and friends do a proper shutdown already, it's just
    ubiquity-dm which is racy here.

I checked by booting the 20150421.1 image to the live DE and then upgrading ubiquity.
