One problem you will run into is Ubuntu 22.04 will update MythTV to 
version 32, or at least it does with the computers here running 
Frontends.  MythTV will only 'see' one version, so a version 29 will not 
see a version 32.

 From my notes to update to Ubuntu 22.04 while staying at MythTV version 
31 (hopefully work for your version 29):


Keep system from upgrading from the desired version. No need to set a 
specific version.

|sudo apt-mark hold mythtv-frontend|

sudo apt-mark hold libmyth*

Had found there were numerous libraries so why the use of the wildcard.


Then do your OS upgrade.  Quite frankly this isn't foolproof: I had one 
Frontend going from 18.04 --> 20.04 --> 22.04 (you can only go one 
version at a time) which didn't like a certain libmyth file, copied 
(then renamed), did an update/upgrade and it was fine, re-held the file, 
and the rest of the transition to Jammy Jellyfish went fine.  I have 
another Frontend which is still complaining about some file not being 
current and so is stuck at 20.04 -- at least have a couple of years to 
figure that out!


Good Luck!
