I think I managed to upgrade from 14.04.1 to 16.04.1, but after I restarted it, it had a black screen. I shut it down and restarted it, then I hit F12 for advanced settings secure boot, and now I only have a terminal, and I'm not sure why. How do I get Ubuntu to operate normally?

The error message describes that you have packages that are broken, for whatever reason. This could have been caused by a bad dpkg command being ran in the past or power was lost during an update, etc.

As the error describes you need to run:

sudo dpkg --reconfigure -a

which means "reconfigure all my packages" which will validate the integrity of files on disk and ensure configurations etc. are not corrupted.
