I am guessing that you have upgraded your system as well as your
MythTV version.  A while back, there was a major change to lirc, the
software that runs the infrared remotes.  A lot of the lirc drivers
where moved into the kernel and how it works was substantially changed
to match that.  Your symptoms are what you get if lirc is not working
and the IR driver code is sending keystrokes to the keyboard system
instead of lirc.  Only the arrows and a few other keys (volume and
power) will do anything as they are matching keystrokes that the
system recognises.  All the other keycodes do not match and are

So you basically need to start from scratch with your lirc
configuration and make it work again.  On top of that, the lirc
packages for Ubuntu since that change are broken and the Python
programs now used to configure lirc will not work as there is a
missing .so library file.  I have written fix scripts for the Ubuntu
18.04 LTS, 20.04 LTS and 21.10 versions, available on my web server.
There are also some other problems that are fixed by the scripts.


The scripts will install a working lirc for you.  It is probably best
to uninstall the existing lirc package first, so you get a clean lirc
install.  Make sure you keep copies of your old working lirc
configuration for reference.

There are some threads on this mailing list that should tell you all
you need to know.  This wiki page tells you where to find the
searchable archive for the mailing list, and searching it for the
above script file names should find the relevant threads:
