I was pretty neutral towards Ubuntu, up until an automatic system update removed my deb Firefox and replaced it with the snap version, even though I specifically set the apt repo to a higher priority.
The entire reason I left Windows is because I don't want (for example) Edge shoved down my throat after every update, and yet Ubuntu has gone and done the exact same thing with snaps.
After literal hours of fighting, the only solution I found was to fully disable automatic updates. With Pop OS I have all the benefits of Ubuntu, but I also get a company (System76) that does cool stuff and doesn't try shoving snaps down my throat.
This program is a client for the very solid Tvheadend TV streaming server. Tvheadend supports pretty much any source you can think of, but is a little more complicated to setup.
Tvheadend is a selfhosted service meant to be run on your own server with your own TV dongles / IPTV channels / etc.
If you only want to watch TV on your PC, doing so with something like Kodi is probably a better idea, as Kodi also supports USB tuners and is simpler to setup (doesn't require a separate server).
