That would seem to indicate the Ubuntu Mantic installation process is creating the bpool with zfs flags that are incompatible with grub. I wonder if the problem is still present in Noble Numbat/24.04? Are you able to check which zfs flags/features are set after the bpool is created? (use `zpool get all bpool` to get flags) You will need to backup your /boot directory and recreate you bpool with the `-o compatibility=grub2,ubuntu-22.04 \` option, as described earlier in this thread. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2041739 Title: update-grub giving errors and apparently not locating /boot on correct zfs pool after upgrade to Ubuntu Mantic To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/2041739/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
