I had the idea to start doing some apps with python for quite some time, so yesterday I thought to give Kivy a try. My system is a Ubuntu 16.04.2-version, and I followed the tutorial here https://www.digitaljunky.io/make-a-snake-game-for-android-written-in-python-part-1/ to download all the necessary packages. Unfortunately I am not able to get the simple 'hello-word-app' as described in that tutorial (and many others) running with buildozer. It shows the following error (just showing the last few lines, if you need more just tell me!):
[INFO]: STDOUT (last 20 lines of 149):

This is the end of the buildozer output with the log_level=2, but the errors don't tell me anything. The permission denied might hint at a write/read problem, but giving read/write permissions to all users for that folder had no effect whatsoever. Any ideas where the problem lies? I also looked on overstack but couldn't find an answer to my problem... Any help is greatly appreciated!
