[Bug 2062179] Re: ugrading grub breaks ubuntu system boot (UEFI, BIOS), if root on zfs

[Thomas Schweikle]

Yes. Same message for Ubuntu or debian:

The UEFI loader does not find the file given. With VirtualBox I could
read the message. With KVM it was impossible to read it. But it seems to
be the very same message: failed to load Boot0001 "UEFI ....: not found"

Title:
  ugrading grub breaks ubuntu system boot (UEFI, BIOS), if root on zfs

Status in grub2 package in Ubuntu:
  New

Bug description:
  Upgrading a root on zfs system will break this system. This is for:

  - 22.04 -> 22.10
  - 22.10 -> 23.04
  - 23.04 -> 23.10
  - 23.10 -> 24.04

  - 22.04 -> 24.04

  Workaround: set all grub packages on "hold" before upgrading.
  If you do not, you'll lose booting possibilities, wrecking your system.

  This is for UEFI-Booted system as for BIOS booted systems, as long as
  these are installed with root on zfs.

  It is for UEFI-Booted systems regardless they are installed with root
  on zfs or llvm+ext4.
