Public bug reported:
I just upgraded from 18.10 to 19.04 and then to 19.10.
I have had ZFS installed in this machine for years. My Root pool is on
LUKS encrypted SSD's which are morrored by ZFS.
The upgrade from 18.10 to 19.04 worked as expected with no errors. And
I was able to reboot, unlock the disks and boot ubuntu 19.04 fine.
When i then did the upgrade to 19.10 using do-release-upgrade, I got errors
installing grub, the 5.3 kernel and friendly-recovery
They reported that they could not find my root pool.
I did not reboot after the upgrade, and tried to run zpool to see if
there was any issue and found zpool was not installed after the do-
release-upgrade. It WAS installed prior to running do-release-upgrade.
So do-release-upgrade did not upgrade my previous zfsutils-linux
package, it seems to have removed it.
Without rebooting, i ran:
sudo apt install zfsutils-linux zfs-initramfs zfs-zed
All of these packages were missing, and they installed correctly.
strangely however the zfs-dkms package was upgraded correctly and still
installed.
This caused the initramfs to be rebuilt, and grub to report no more
errors, fixing the issue for me.
