Just upgraded this AM:

joe blow

tvheadend:
Installed: 4.3-2425_gd431956ccbookworm
From:
4.3-2424_gbfcc00142bookworm,

I think that was the previous version.
Had it all set up the way I wanted,basically running on a different port.
The upgrade over wrote /etc/systemd/system/multi-user.target.wants/tvheadend.service file
The service started, but of course running on the original port 9981, had to edit the tvheadend.service file to restore my wants.
Is there a method to prevent this over writing?
Thanks

joe blow

Would:
chatrr +i prevent the upgrade from continuing?
Also it did not change:
/etc/default/tvheadend

Don't try and change a systemd file that is supplied by a package. Instead use
sudo systemctl edit whatever.service
which will create an override directory and a file within it.
I expect your distro has documentation about this. If not see:
