you don't have the Intel gfx driver installed, libva seems to be the wrong version..
In short, you didn't follow the howto

 The gfx driver was not installed. Thank you very much! 
But i have followed the complete tutorial 3 times and it didn´t work for me with i5 9600k.
With i5 4000 series and amd 5600 it worked perfectly.
The problem with i5 9600 has been solved with this commands:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade -y

and this was ubuntu 18.10, not 16.04

happy holidays and thank you so much for your help!
