Ah.  I think the reason I was confused about your installation is
because you have this in it:

    > Add the mythtv respository with 'sudo add-apt-repository ppa:mythbuntu/31'

...even though Ubuntu 20.04 (don't know about Xubuntu) already comes
with some version of v31 visible even without installing any PPA's.
So you're using a PPA but not also running MCP.
