Immediately works, though it appeared my system only needed to install duplicity and python-pi was already at the newest version and did not install.
The issue appeared on my laptop; I don't recall an issue with any desktops here. (Don't know if that piece of trivia helps track down the problem source.)
What corrected for me was Seth's post in https:/ /bugs.launchpad .net/deja- dup/+bug/ 1606449 of:
sudo apt install duplicity
sudo apt install python-gi
