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.
