Vanilla GNOME metapackage

 This package depends on the core GNOME packages with minimal Ubuntu
 branding similar to what was offered by Ubuntu GNOME. Ubuntu GNOME
 was an Ubuntu flavor that offered a mostly pure GNOME experience until
 it was discontinued after the 17.04 release.
 .
 It is also used to help ensure proper upgrades, so it is recommended that
 it not be removed.
