Public bug reported: I've been running Ubuntu 20.04 daily builds for about a month. Within the past several days, something broke with grub where it is no longer able to probe my ZFS datasets in order to build up its menu. This had been working fine, aside from the issue #1867007 I previously filed, so I believe this is a regression. As a result of it, I'm unable to update my kernel.
I noticed it when trying to perform a dist-upgrade, but it's reproducible running `grub-update` on its own: ❯ sudo update-grub [sudo] password for nirvdrum: /usr/sbin/grub-probe: error: failed to get canonical path of `rpool/ROOT/ubuntu_bp7ow2'. ❯ zsysctl list ID ZSys Last Used -- ---- --------- rpool/ROOT/ubuntu_bp7ow2 true current I realize that's not much information to go off of. Please let me know what other diagnostic information you would need. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New ** Description changed: I've been running Ubuntu 20.04 daily builds for about a month.
