Hi Steve,

The computer still boots successfully!

So now I have two directories in /boot/efi/EFI, one called "ubuntu" and
the other called "Ubuntu 16.04.2 LTS".

1. Would you recommend I remove the older Ubuntu 16.04.2 LTS directory?

2. Do you think this problem will occur again for future updates?

Some more info:

The ubuntu directory has a plist file in it that says product version
2.02~beta2-36ubuntu3.12

The Ubuntu 16.04.2 LTS directory has a plist file in it that says
product version 2.02~beta2-36ubuntu3.9

When I boot the computer it only shows the newer version
2.02~beta2-36ubuntu3.12.

Thank you very much for your help!
