[Bug 1811502] Re: release upgrader wants to remove itself

[Brian Murray]

This is likely because you don't have a desktop metapackage installed on
your system:

2019-01-12 10:46:56,829 DEBUG none of the '['ubuntu-desktop', 'kubuntu-
desktop', 'xubuntu-core', 'xubuntu-desktop', 'ubuntustudio-desktop',
'mythbuntu-desktop', 'kubuntu-netbook', 'lubuntu-core', 'lubuntu-
desktop', 'ubuntu-gnome-desktop', 'ubuntu-mate-core', 'ubuntu-mate-
cloudtop', 'ubuntu-mate-desktop', 'ubuntukylin-desktop']' meta-pkgs
installed

Please install the appropriate one for your desktop environment and try
the upgrade again. Thanks and good luck!
