Bug Description
Binary package hint: grub
My last Natty update was few days ago.
I just updated my (previously) working Natty on MacBook Pro and the process was stuck during the grub update (the last lines displayed were the list of kernel found and memtest86).
Ctrl+C helped to stop the update but grub and new kernel 2.6.38-8 packages installation were not finished.
dpkg --configure -a was stuck too.
A reboot was a bad idea because grub doesn't load.
I managed to boot on a livecd and chroot.
dpkg --configure -a helped me finish the installation but grub displayed "This GPT partition label has no BIOS Boot Partition...".
I am now stuck because grub is not loading at boot and it won't reinstall (same GPT BBT error).
Is there any manual way to revert to a working boot/BBP/grub?
Thanks.

It's difficult to say if this is a bug in grub, unless the bug is that grub hangs when re-installing the bootloader.
But, to see if it hangs again, you could try reinstalling grub after booting from a CD. If you're booting from the live CD, running
sudo grub-install /dev/sda
(assuming that is your one and only disk, which is generally the case on a MBP).
Or if you are booting from the 'alternate' CD, there is a menu option to reinstall grub. If the one doesn't work, try the other. And report if either one of them hang, or give you any other errors.
Also, if you could post your current partition layout, that might help someone debug this, e.g.
sudo parted -l
