Comment 3 for bug 1845333

This bug was fixed in the package grub2 - 2.04-1ubuntu9

---------------
grub2 (2.04-1ubuntu9) eoan; urgency=medium

  * debian/patches/ubuntu-zfs-enhance-support.patch:
    - Handle case of pure zfs only snapshots giving additional "}", and as
      such, creating invalid grub menu.
      Spotted by grubzfs-testsuite autopkgtests.

grub2 (2.04-1ubuntu8) eoan; urgency=medium

  * debian/patches/install-signed.patch -> ubuntu-install-signed.patch:
    Really fix the installation of UEFI artefacts to the distributor path (we
    only want shim, grub, and MokManager, and shim's boot.csv there), and to
    the removable /EFI/BOOT path (where we want shim and fallback only).
    Rename the patch to ubuntu- like others that are Ubuntu-specific or
    otherwise modified to avoid such confusion at merge time in the future.

grub2 (2.04-1ubuntu7) eoan; urgency=medium

  * debian/patches/ubuntu-zfs-enhance-support.patch:
    Disable history entry under some conditions:
    - Don't show up if the system is a zsys one and zsys isn't installed
      (LP: #1845333)
    - Don't show for pure zfs systems: we identified multiple issues due
      to the mount generator in upstream zfs which makes it incompatible.
      Disable for now (LP: #1845913)
