[EXTERNAL] Canceled do-release-upgrade

I was upgrading a headless unit from Ubuntu server 14.04 to 16.04 when I accidentally hit Ctrl-C.  The result was the process aborted and wouldn't restart ("another process is running").  I searched the web and came up with a few possibilities.  I removed the lock and lock-frontend files, at this point 'dpkg --configure -a' appeared to re-launch the process which proceeded but ended with errors.  I made some configuration file changes and rebooted, the initial Ubuntu startup screen didn't even appear.

Obviously I made a (or multiple) mistake(s).  Now my question is "What can I do to recover using Live media?"  I presume I could do a re-install without formatting the root file system but I'm wondering if there's a less drastic approach and order of things I should try.  Thanks for your help.
