The Ubuntu project regularly release new versions of Ubuntu every six months.
For example, Arch Linux uses a rolling release cycle. Depending on your distribution, they may not even see much testing before they’re released as stable updates.
First of all, an important terminology clarification in regards to this article is needed, as when we refer to "Live TV" here we are only talking about traditional broadcast television systems using standard digital television or analog television, like you normally receive through a coaxial cable from a Television antenna, cable, or satellite dish.
This means that the Live TV reception to your house comes foremost from terrestrial television signals using a cable television, satellite service, or over-the-air television using a physical TV-tuner adapter or network attached TV-tuner appliance hardware.
Otherwise, you’d have to wait for the next major release of Ubuntu.
You get the latest version of all your software by upgrading from one frozen-in-time version of the Linux distribution to the next frozen-in-time version of the Linux distribution.
