package grub-common 2.02~beta2-22ubuntu1.1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

[iMac]

Just a regular upgrade getting ready to bump to 15.10.

Grub-common failed with a systemd error that seemed to be related to a dbus timeout of sorts. Anyways, if the info here is helpful, not sure what happened.

I had returned from suspend just prior to initiating the upgrade.

A reboot and dpkg -reconfigure followed by the upgrade again solved it.

Maybe some sort of dependency issue with systemd/dbus and the new grub-common.
