Flole patfenton One thing I have not tried is removing tvheadend as I just expect it will install my version again and I'll lose all my configuration for no reason. As long as you don't purge a package all configuration files are preserved, thats the default for most (if not all) deb packages btw.
patfenton sudo apt remove tvheadend # OK sudo apt install tvheadend # OK As expected, ended with the same old version again. But thanks for responding. Are you really sure that the repo has a newer version in it?
DaveH I note somewhere above it says you are running raspbian buster on your pi. I don't claim to be an expert but I can't find anything except a lot of bookworm and a few bullseye packages for raspbian. So I'm not surprised your upgrade ends with nothing to do. You need to upgrade your pi first, and ideally swap it for a newer one, I suppose.
patfenton Yes Dave, ancient. about 5 years old. It came bundled with this OS. Definitely I need to a buy a newer one.
patfenton Raspbian came installed on the RPi 3 B+ and has been very stable. I upgraded the OS recently. sudo apt full-upgrade.
