Title:
  grub in xenial fails to read pc-linux 4.15 kernel snap

Status in grub2 package in Ubuntu:
  Fix Released
Status in grub2 source package in Xenial:
  Fix Released

Bug description:
  The grub version in xenial fails to read the pc-kernel 4.15 kernel
  snap.

  [Test Case] To reproduce (thanks to Colin for the grub-fstest hint):

  $ snap download pc-kernel --channel 18
  $ grub-fstest pc-kernel_192.snap crc /vmlinuz

  This fails with the xenial grub with:
  grub-fstest: error: read error at offset 8096256: invalid xz chunk.

  but it should work (it works correctly with the grub2 from bionic and
  later).

  Colin pointed to
  https://git.savannah.gnu.org/cgit/grub.git/commit/?id=951306c5094d2bfb46d5baedfde84a2015c4a3fa
  which may fix the issue.

  [Regression Potential] The fix is in GRUB's squash4 module, so only
  workloads that involve reading squashfses could be affected.
