Public bug reported: on trying to upgrade grub-pc today to version 2.02-2ubuntu8.1, I get the following error on my server with ZFS root:
Setting up grub-pc (2.02-2ubuntu8.1) ... /usr/sbin/grub-probe: error: failed to get canonical path of `rpool/root'. dpkg: error processing package grub-pc (--configure): installed grub-pc package post-installation script subprocess returned error exit status 1 Errors were encountered while processing: grub-pc E: Sub-process /usr/bin/dpkg returned an error code (1) ZFS root worked fine with grub-pc prior to this package release, so this feels like a package regression.
