As a workaround:

sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled

sudo apt-get -f install
sudo apt-get install ubuntu-desktop

 sudo mv /usr/share/dbus-1/services/org.freedesktop.Notifications.service.disabled /usr/share/dbus-1/services/org.freedesktop.Notifications.service
