Bug Description

Test Case

Choose gdm3 when prompted.
Restart your computer.

The bug is that gdm refuses to start

Install gnome-session

More Info
For smoother upgrades and to allow the option of a more vanilla GNOME experience, it was decided to try to continue to use an ubuntu-session package by default containing an "ubuntu" session that identifies as "Ubuntu" and runs GNOME. We don't want or need the GNOME sessions in the default install.

This is more fallout from so let's try reverting that change.
