Actually, just choosing to resurrect the screen window will restart the upgrade process which then will warn you about an upgrade not succeeding and then if you exit that sources.list.distUpgrade will be restored.

I tried messing with screenrc and adding "onerror" to zombie (https://www.gnu.org/software/screen/manual/html_node/Zombie.html) but that did not help.
