[Bug 2107681] Re: dpkg can not remove broken package

[Julian Andres Klode]

It's plausible to consider this user error and mark the bug as invalid;
the /boot/grub directory shouldn't disappear (is /boot not mounted for
some reason?). But also perhaps it should try update-grub as a best
effort only.

** Package changed: grub2 (Ubuntu) => ubuntu-realtime (Ubuntu)
