I didn't upgrade but installed a new frontend with Lubuntu 22.04. And 
beneath mythtv-frontend and libmyth, I had to "apt-mark hold" 
mythtv-common too.

Actually, I did a downgrade:

- first install mythtv-frontend that comes with Lubuntu 22.04, aka 
version 32, then remove the packages mythtv-frontend, libmyth and 
mythtv-common without removing dependencies

- then install version 31 of the three above mentioned packages (one 
requires a further package as a dependency, but I can't remember which one)

You can download the packages from here:
