[Bug 972250] [NEW] "This GPT partition label has no BIOS Boot Partition"

[Tomi Pieviläinen]

Public bug reported:

On a system installed with 11.10 and upgraded to 12.04 last week, today
grub fails to apt-get upgrade with this error in /var/log/apt/term.log:

/usr/sbin/grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.
/usr/sbin/grub-setup: warn: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/grub-setup: error: non-sector-aligned data is found in the core file.

The system has luks+lvm as installed by 11.10 alternative installation
cd, and indeed seems to have GPT but no BIOS partition (system is
running BIOS on Asus F1A75V-PRO motherboard).

** Affects: grub2 (Ubuntu)
     Importance: Undecided
         Status: Confirmed
