Bug Description

After installing with ubuntu-oneiric-alternate-amd64+mac.iso (ISO from 2011-09-21) this MacBookPro6,2 is not bootable. I used the 'guided resize' partitioning option to split an existing ext4 partition to make space. The original system was working fine and the resulting partition table, after the install, looks reasonable (two ext4 partitions, two swap parititons, and a bios_grub partition).

This would appear to be a regression. If I remember rightly, this worked correctly in Oneiric once before.

Also occurs with kubuntu-oneiric-desktop-amd64+mac.iso . I.e. it's not specific to debian-installer.

Looking at the data collected in this bug report by apport we can see there is an issue with the debian-installer source package hook and its ability to collect dmraid information. (Its failing because the commands are not executed as root.)

The partition table looks empty. I'm attaching sfdisk output, as well as the installer logs again (syslog, partman, installer/debug).

For the latest install, I'm using ubuntu-oneiric-desktop-amd64+mac.iso from 2011-09-22

I installed libparted0debian1 version 2.3-6ubuntu3+ppa1 from ppa:cjwatson/ppa into the live session and had the same result. The system does not boot after install. Will attach installer logs.

Seems to also occur when doing an in-place upgrade (from Oneiric to Oneiric).

I started from a working Oneiric system (from ubuntu-oneiric-desktop-amd64+mac.iso from 2011-10-11) which was installed with "guided: entire disk" partitioning (i.e. using ext4).

I booted ubuntu-oneiric-desktop-amd64+mac.iso from 2011-10-12 and chose the upgrade option.

It's not clear if the cause is the same, but the symptoms (that the installed system does not boot) are the same. The installation appeared to finish normally.

Same here. Installed on MacBookPro3,1 and MacPro6,2. Both are unable to boot. Workaround: boot using the live cd into the first partition, install gpttools and run gpttools /dev/sda, reboot.

For the record (and before I forget), the problem here is that the EFI System Partition / BIOS Boot Partition (whichever it is) isn't being recognised as such by partman/libparted and so isn't getting the correct (indeed any) MBR partition type when gptsynced, which causes libparted to revert to protective MBR style, which causes everything to fall over in a heap.

Cengiz, you mention the "gpttools" command, which is also included in the 11.10 release notes, however there is no such package nor command that I can find. Can you please be more specific? Are you talking about gptsync?

So, I think I've managed to fix this. Unfortunately, I don't actually have hardware to hand so that I can test it directly. I've written a test script which exercises as many cases as I can think of, and they all pass now, but the real test will be trying this on actual hardware. As such, please try tomorrow's daily build, and if it still goes wrong then please do let me know and reopen this bug.

parted (2.3-8ubuntu4) precise; urgency=low

  * At least some Intel Macs get rather upset if we revert to a protective
    MBR, so try harder to avoid this and to do a better job of writing a
    hybrid MBR:
    - Write a type code of 0x83 for more filesystems, and 0xda for
      non-filesystem partitions.
    - Do not rely on filesystem probing to recognise EFI System Partitions.
    - Write a protective partition starting at LBA 1 if we find an EFI
      System Partition or BIOS Boot Partition in the first position, even if
      it does not really begin at LBA 1 (LP: #856826).
    - Ensure that protective partitions corresponding to an ESP or BBP
      always have starting cylinder 0, head 0, sector 1.
    - Don't revert to a protective MBR just because the first GPT partition
      wasn't recognised as anything in particular.
    - Add tests for hybrid MBR syncing.
