[Bug 2047173] Re: grub-probe: error: compression algorithm inherit not supported

[James Dingwall]

My opinion is that "Won't Fix" is not the correct action for this bug:

- it is an acknowledged issue in grub which is now resolved
- it is a regression in that previously functioning systems with a bpool configured according to guidelines stops working after upgrading to the latest Jammy HWE kernel when a pool level snapshot is created
- my failed attempt to workaround the problem using the package from 24.04 suggests that the forthcoming LTS release could be susceptible to this problem

Title:
  grub-probe: error: compression algorithm inherit not supported

Status in grub2 package in Ubuntu:
  Won't Fix

Bug description:
  I've reinstalled several times already, .. sometimes it works for a
  while sometimes the issue is there instantaneously, but grub can't see
  uuid of zfs file systems.

  When I boot live I can import them just fine, can't boot the system as
  grub marks them as unknown filesystems.
