Installation Issues on Xubuntu 18.04

I read Justin Abrams issue at #797 but are continuing to get similar errors. Any suggestions would be appreciated.

You either need to downgrade Kivy to v1.11.0 or upgrade Python to v3.x

Try doing Kivy first as this is probably easier:

sudo pip uninstall Kivy
sudo pip install Kivy==1.9.1

Did you install using pip install -r requirements_linux.txt?
