Just thought I would add the salient findings from Bug #2041739.
* update-grub/grub-probe fails when the `feature@extensible_dataset` flag is enabled on bpool
* this happens when the bpool is created without the `-o compatibility=grub2,ubuntu-22.04` compatibility flags and a subsequent snapshot is taken.
* a successful work around is to backup bpool and recreate it using the `-o compatibility=grub2,ubuntu-22.04` flags
Further thoughts:
* apparently problem is still happening with fresh Ubuntu Noble Numbat installations, which implies NN installation process not creating bpool with correct compatibility flags
* problem should be fixed in grub, but work-around compatibility flags works as long as they are used consistently
* I am not sure how our findings relate with the discussion around kernel/module versions. I am using the latest version of Ubuntu Mantic with kernel version 6.5.0-28-generic successfully. I also have linux-genereic-hwe-22.04-edge package installed on my system.
