[Bug 1990143] Re: grub-common update to 2.06-2ubuntu11 broke zfs root boots

[Julian Andres Klode]

There seems to be a bug in when the patch series was cleaned up by
importing it into the gbp pq and re-exporting it, it dropped the last
two lines from the patch. It's unclear what is happening there.

However, the patch seems to be invalid: Even quilt pushing the original
patch does not produce those lines even though they are in the pach.

** Changed in: grub2 (Ubuntu)

Title:
  grub-common update to 2.06-2ubuntu11 broke zfs root boots

Status in grub2 package in Ubuntu:
  New

Bug description:
  Running update-grub after updating to grub-common (2.06-2ubuntu11)
  causes this issue:

  sudo update-grub
  Sourcing file `/etc/default/grub'
  Sourcing file `/etc/default/grub.d/init-select.cfg'
  Generating grub configuration file ...
  /etc/grub.d/10_linux_zfs: 1135: Syntax error: end of file unexpected (expecting "fi")
  Memtest86+ needs a 16-bit boot, that is not available on EFI, exiting
  Warning: os-prober will be executed to detect other bootable partitions.
  Its output will be used to detect bootable binaries on them and create new boot entries.

  This leads to a grub prompt at boot.

  Reverting to grub-common (2.06-2ubuntu7) fixes the issue:

  sudo update-grub
