[Bug 1620589] [NEW] unattended-upgrade stuck because of "unknown filesystem" from os-prober

[Timo Aaltonen]

Public bug reported:

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?
