OK, I'm new with the Debian community and don't want to make os-prober
author upset when I still don't know my ass from a hole in the ground.
So I'm checking to see if this is "bugish" behavior to you.
I've got os-prober
$ dpkg -l | grep prober
ii os-prober 1.42
utility to detect other OSes on a set of drives
However, it does not find the Ubuntu partitions
$ sudo update-grub
Generating grub.cfg ...

Meanwhile, I've learned I can manually insert the Ubuntu stanza in
grub.cfg and it does bring up Ubuntu system.
menuentry 'Ubuntu, with Linux 2.6.38-8-generic' --class ubuntu
--class gnu-linux --class gnu --class os {
recordfail
set gfxpayload=$linux_gfx_mode
insmod part_msdos
insmod ext2
set root='(/dev/sda,msdos3)'
search --no-floppy --fs-uuid --set=root
