Comment 10 for bug 1264887

Looking at the ubuntu-release-upgrader code we see the following:

        for key in metapkgs:
            # if it is installed we are done
            if key in self and self[key].is_installed:
                logging.debug("need_server_mode(): run in 'desktop' mode, (because of pkg '%s')" % key)
                return False
            # if it is not installed, but its key depends are installed
            # we are done too (we auto-select the package later)
            deps_found = True
            for pkg in self.config.getlist(key, "KeyDependencies"):
                deps_found &= pkg in self and self[pkg].is_installed

KeyDependencies for kubuntu-desktop are:

[kubuntu-desktop]
KeyDependencies=kdm, kubuntu-artwork

Are there some other packages that should be added?
