First make sure that Ubuntu's /boot/grub/grub.cfg contains a menuentry
for Ubuntu in the section starting with
### BEGIN /etc/grub.d/10_linux ###
If not, run update-grub in Ubuntu.

Once it does, run update-grub in Debian.
If Ubuntu still is not detected for some reason, you can always copy
the menuentry from Ubuntu's /boot/grub/grub.cfg to
Debian's /etc/grub.d/40_custom, and run update-grub in Debian once
again.
