If you are running Kodi in Ubuntu or other Linux distro, then PVR clients are not installed by default. Follow the instructions in Ubuntu instead:

Ubuntu PVR add-ons



Or simply (should the link ever become inactive):

NOTICE:
If you don't already have the Team Kodi (team-xbmc) PPA added, then you will need to do so in order to install the PVR client add-ons (see here). If you're not sure, you probably already have it installed, as that is how you normally install Kodi in the first place.


Exit (Quit) Kodi if it is already running and open a terminal window


Type in
sudo apt-get update
and enter your password when prompted


Type in
sudo apt-get install PACKAGENAMEHERE
but replace PACKAGENAMEHERE with a package name from the table below.


example:
sudo apt-get install kodi-pvr-iptvsimple

The PVR client add-on should now be installed. If Kodi was already running, restart it to load the add-on.
