error when installing - error: failed to get canonical path of 'aufs'

[noexit]

Good morning, All! 
This is my first post to the Ubermix forum, so please accept my gratitude for you help!

I have an Ubermix (16.04) install on my kid's laptop.   I notice the following error when trying to install or update: 

Setting up friendly-recovery (0.2.31ubuntu2.1) ...
/usr/sbin/grub-probe: error: failed to get canonical path of `aufs'.
dpkg: error processing package friendly-recovery (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 friendly-recovery
E: Sub-process /usr/bin/dpkg returned an error code (1)

I'm also experiencing an issue rebooting wherein the OS complains that gnome-keyring-daemon (Not responding) is still running.  Telling the system to Restart Anyway will yield no result.  Instead reboot must be completed by Terminal via sudo reboot

Not sure if these two issues are related, but they seemed to have started when I attempted a boot recovery from the USB installation media after the system would not boot following a power failure.

I'm new to Linux and certainly new to the way Ubermix sets its system up.  My goal is to get the "customizations" I've made saved to the default image as I believe is intended.

Any guidance is graciously appreciated!
