Kodi NextPVR Client for Ubuntu 16.04... not showing up..

[Zbugsii]

I am at a loss here... I am using Kodi 17.1 on a Odroid C2 platform with Ubuntu 16.04. When I go and add NextPVR using the Linux commands as per Kodi wiki... all seems to do as required, but when in Kodi, I never find the client. My backend NextPVR is up and running on a windows 10 box and I know it all works because my other Windows PC has Kodi on it and uses the backend just fine.

Can anybody give me any help on this or point me in the right direction... or?

Thank you
