"No sign of Debian" is not our responsibility; contact Ubuntu about it.

Ubuntu installs its own GRUB to the MBR. However, the menu it produces
should show all the other OSs.

You would experience the same if you installed another Debian to another
partition. It installs its own GRUB to the MBR and produces a new menu.
If that menu did not have all the other OSs it would be a bug. We would
then spring into action.
