A search on Stack showed this page: https://askubuntu.com/questions/697190/fsck-error-on-boot-dev-sda6-unexpected-inconsistency-run-fsck-manually

I ran the utility, and answered yes to about 20-30 items. I have no idea what to do, but I figured this was worth a try. Once this completed, I rebooted again.
