I wouldn't recommend giving up on the GUI. It's doing what it's supposed to do. And in your case, it's letting us know something is odd. The GUI also more than likely produces a log even when you cancel out of the process. I just don't know where that log file is. Perhaps someone else will chime in.
Did you try Edit, Fix Broken Packages within Install/Remove Software?
Also consider Lite Tweaks (Menu, System, Lite Tweaks). The Autoremove Packages and Package Cache are safe options.
Just as a heads up, it appears the GUI updater is a script run from /usr/scripts/updates-gui and it generates a log in /var/logs/llupdates.log. However I'm not sure if this file is generated line for line while the updates are running, or if it is only generated after the updates are done all in one shot. Just wanted to let you know, since I was able to track these down.
