FYI, There have been a number of updates this week for mythtv v31-fixes 
on Ubuntu 18.04 so I did  mythtv mythtvplugins install on a fresh 
Xubuntu 18.04.4 system.

The error on mythweb still exist and the fix Mike mentions about sudo 
apt --fix-broken install (run it twice) followed by audo apt install 
mythplugins, still works.
