 Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

[Matteo Settenvini (tchernobog)]

I've found the culprit. This bugs still occurs for me, and its not grub's fault.
On powerpc machines, the bootloader (grub2 along with yaboot) are put on a separate partition, which is HFS formatted.

I mount this partition as /boot/grub.

The problem is with hfsutils: even if they report (e.g. via the output of "mount") that this filesystem is mounted read-write, after an abrupt halting of the machine it's mounted read-only. The only real fix is to manually unmount /boot/grub, run fsck on it which clears the dirty flag, and then remounting it and running grub2 installation again.

So I believe that fixing the output of mount, or forcing a fsck when mounting a hfs volume, is the only real solution to this.

Or whenever the filesystem gets dirty, and update-grub is called, you'll get errors, potentially leaving your system unusable.

[Matteo Settenvini (tchernobog)]

Sorry for the confusion, the last comment is about Bug #410522, which probably is different from this (and thus incorrectly labeled as a dupe). Also the reference to hfsprogs is for that.
@Artur: on what architecture are you on?

[Artur Rona (ari-tczew)]

@Dimitrios: I don't now whether new version fixing this bug, because this bug was very arduous and I did workaround about this issue previously.

@Matteo: 32bit.

[Dimitrios Symeonidis (azimout)]

@Artur: what is the workaround you implemented?
@Matteo: should we remove the duplicate?

[Matteo Settenvini (tchernobog)]

@Dimitrios: yes, please, remove the dupe. I will update the other bug accordingly.

[Artur Rona (ari-tczew)]

I did it very long ago, so I'm writing about it from my 'mind'.

1) make backup /boot
2) purge packages grub2, grub-pc and related
3) clean /boot
4) remove out-of-dated kernels
5) install latest grub2/grub-pc
6) install latest kernel
7) merge your boot-backup directory with original: if any files which no exist in /boot directory, copy from backup directory to /boot (no overwrite if exist!); including files from /boot/grub like .mod files

[Artur Rona (ari-tczew)]

I'm marking this bug as Invalid because I think that it's not important and very hard to reproduce.
