That is weird.  Is MySQL or MariaDB installed?  One or other is
required for MythTV and might cause that, but usually MySQL is
installed by default.  Exactly what version of Ubuntu are you
installing?  Is it a server version?  I would recommend Xubuntu
18.04.1 as the best version for a normal MythTV box, but it depends on
what other things you want to use it for, and having it in a VM sounds
like you just want to run a backend only system.

And before you install MythTV, I would recommend uninstalling MySQL
and installing MariaDB instead.  Doing that after MythTV is installed
is a pain, and MySQL's command line is now a pain as it no longer uses
the readline library and consequently does not do command history
properly.

Also, did you run "apt update" after adding the PPA?

You might like to install the synaptic package (and apt-xapian-index
for synaptic's quick index feature) and see if it can tell you more
about the dependencies involved.
