@SoXX It doesn't look like inputstream.adaptive is installed, to install it on Ubuntu I believe it is "sudo apt-get install kodi-inputstream-adaptive' Then to enable it in Kodi it is Add-ons - My Add-ons - VideoPlayer Inputstream - InputStream Adaptive. May need to restart Kodi after for the YouTube add-on settings become available. In the YouTube add-on settings you want Settings - MPEG-DASH - Use MPEG-DASH and Use mpeg-dash proxy enabled.
