[Bug 1685821] Re: GRUB issues package shim-signed 1.27~16.10.1+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Thanks for the follow-up - I was in fact just about to post saying that
it appears you were trying to install shim on a system not booted in
UEFI mode, which is not expected to work.  Glad you have the system
working now, and closing this bug as invalid.

** Changed in: shim-signed (Ubuntu)

Bug description:
  Sorry to cause you to have to help. I am 70 years old and not as quick as I used to be! I have multiple drives and partitions (Linux) but would be happy to have all under one boot handler. If the data can be recovered and integrated, awesome. If not life goes on. I also have Windows drives and was using this system in my old setup. I recently got a new motherboard, CMOS and CPU. The System would present me with a boot menu to choose which system would launch OK with appropriate drivers for the system. So now instead of doing the smart thing and only hooking up one SSD to do set-up I thought "Linux is pretty smart, maybe it will see the old system as was and correct the GRUB to launch the select menu under Ubuntu as before.
  I am going for the upgrade to the new UBUNTU 17 and will let you know how I made out!
  Thank you all so much for the great effort you all put into the packages, and releases.
  I am retired but if I win a lotto I will make a large donation.
