the linux build produced an AppImage without kivy:

  user@disp6152:~/Downloads/artifacts0$ ./helloWorld.AppImage
  Traceback (most recent call last):
    File "/tmp/.mount_helloWxxC0Dh/opt/src/main.py", line 4, in <module>
      from kivy.config import Config
  ModuleNotFoundError: No module named 'kivy'
  user@disp6152:~/Downloads/artifacts0$

Checking the job output, it hit permission issues early on. Huh, in gitlab I think I was root, but I'll add `sudo` and see if the next build works.

  Run build/linux/buildAppImage.sh
    build/linux/buildAppImage.sh
    shell: /bin/bash --noprofile --norc -e -o pipefail {0}
  + PYTHON_PATH=/usr/bin/python3.7
  + apt-get update
