And ran the updater and rebooted. This fixed the problem and Kodi is running again.
Is there a way to get rid of the testing kernel stuff as I do not need it at this stage (was only needed for Wireguard stuff). Can I remove deb http://apt.osmc.tv videoimprovevero49 main and will that go back to stable (once stable version is higher than whatever testing version is installed)?
No, for now you have to leave the testing kernel as that’s what gives you the 4.9 kernel. If you remove that, you won’t get 4.9 updates. If you revert to the older kernel (and you really can’t do that) you’d lose Wireguard.
I’ve been using 4.9 for months, and it’s very stable for me. You shouldn’t worry about being on 4.9.
