Been using Ubuntu Gnome Shell since the unofficial 12.04 Gnome Shell Remix. I'm now at 13.04. Today, the Gnome3 Team ppa (https://launchpad.net/~gnome3-team/+archive/gnome3) update is wanting to delete a lot of packages, including account-plugins, Cairo dock, caribou, cheese, compiz, empathy, eog, firefox, gdebi, gdm, gedit, gimp, a lot of gir1.2 items, more disconcerting - gnome-control-center, gnome-core, gnome-icon-***, gnome-panel, packagekit, session, gnome-shell, icedtea, libreoffice, and a lot more. It looks as if it is wanting to uninstall gnome. Any ideas.
