Kivy for Python 3 doesn't run

[Dominik Lang]

I've tested the official python3-kivy package (1.9.1-1build3) on bionic, artful and xenial.
It doesn't work on any of those systems. Here's a simple way to verify, just run in your shell:

python3 -c 'from kivy.base import runTouchApp as r; from kivy.uix.button import Button as B; r(B(text="Hello Kivy"))'

There's an additional problem on artful that prevents both python-kivy and python3-kivy from running, but that's a known bug which can be circumvented by setting multisampling to 0 in ~/.kivy/config.ini.

The Kivy developers maintain a PPA, and the kivy-daily version works on all 3 distros (both py2 and py3). You may want to have a look at it here:

https://github.com/kivy/kivy-sdk-packager/tree/master/linux/debian

Note: Building the package itself successfully is not a guarantee for it to work correctly, because it is designed to run with different backend components.

Also, feel free to contact the devs so this can get sorted out more easily. A few ways to do so are listed here:

If you need more information, I'm happy to assist, too.
