[Bug 1573324] [NEW] something to do with UEFI and backwards compatibilty

[Drone4four]

Public bug reported:

I was doing an advanced installation of 16.04 using epiphany and it
choked when installing grub installer.  After partitioning my drives,
there was a prompt asking me if it would be OK to proceed if certain
other operating systems.  I said OK. Then packages began installing and
it choked at grub-installer.

I installed Boot-Repair and then it asked me to input these three commands:
sudo chroot "/mnt/boot-sav/sda1" dpkg --configure -a
sudo chroot "/mnt/boot-sav/sda1" apt-get install -fy
sudo chroot "/mnt/boot-sav/sda1" apt-get purge -y --force-yes grub*-common grub-common:i386 shim-signed linux-signed*

Here was the output from each: http://pastebin.com/wjkTVbTf

Boot-Repair concluded with an error.  Here is Boot-Repair's info file:

This royally sux.
