grub-efiamd64-SIGNED Package failed

UBUNTU 14.04

During installing Ubuntu along side of Windows 10, I received at message that the GRUB-EFI-AMD64-SIGNED Package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot

I am not sure which version of this package UBUNTU was attempting to installed. This error occurred today, December 2, 2015 and I did select the option to install UBUNTU and 3rd Party updates. Perhaps the date can help figure out the version it was installing, whether part of the original distribution file set or an update.

The relevant error in the logs appears to be:

Can't access efivars filesystem at /sys/firmware/efi/efivars, aborting
