I seem to have update-grub in both /sbin and /usr/sbin and the 2.6.20-5-generic kernel works fine for me :
iks@max:~$ ls -l /sbin/update-grub -rwxr-xr-x 1 root root 616 2006-12-20 17:44 /sbin/update-grub iks@max:~$ ls -l /usr/sbin/update-grub -rwxr-xr-x 1 root root 35685 2006-12-20 17:44 /usr/sbin/update-grub
iks@max:~$ uname -r 2.6.20-5-generic
I suppose you are using Feisty. Did you upgrade from an Edgy isntall or did you isntall it from scratch ?
