Hello
I bought a raspi3 and I love OSMC!
I am using Kodi since manny month, hut in OSMC I cannot find the PVR client for Zattoo and under addons i cannoz install any PVR clients…
Please help 
Kindly regards,
Markus Kühn
Which version of Kodi are you using?
Latest OSMC update from 12.2018…
I don’t know the exact kodi version of this, but it is completely up-to-date.
Have you checked under My Addons?
Yes and there are several Pvr plugins but Zattoo is missing and I cannot install it using usuall way over repository…
Are you on Kodi Krypton or Leia? I just saw that on Leia there is a problem.
He says 2018.12, so I suspect he has not installed a nightly and is on 17.6z. Not even sure if that PVR addon existed in v17.
Thank you - you just gave me the right idea 
Updated to nightly and now I can use Zatttoo!
Thank you cery much
