** Description changed:
The grub version in xenial fails to read the pc-kernel 4.15 kernel snap.
- To reproduce (thanks to Colin for the grub-fstest hint):
+ [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.
** Changed in: grub2 (Ubuntu Xenial)
Status: Triaged => In Progress
