Bug Description

I have a xenial server with ZFS on root, and it seems to have a stuck unattended-upgrade from June because of os-prober, see attached output of 'ps ef'.

Running 'grub-mount /dev/sda1 /var/lib/os-prober/mount' manually gives
error: unknown filesystem.

Perhaps error handling should be better?
