title: Buildozer building an Android Kivy app returns Command failed
body: <p>I'm creating an app in Kivy and tried to build it on a Buildozer virtual machine.
  I followed <a href="https://kivy.org/docs/guide/packaging-android.html" rel="nofollow noreferrer">this tutorial</a> to set it up. Running the <code>buildozer android debug</code> command returns <a href="https://pastebin.com/yqGM3jhE" rel="nofollow noreferrer">this error</a>. </p>
  
  <p>I am not very experienced in Ubuntu so I've hit a wall.
  sf_WKND is the shared folder where main.py is stored along with everything else. I haven't altered the buildozer.spec file except for log_level=2.
  In dependencies I used the Android on Ubuntu 16.04 (64bit) commands. (Which I'm not sure is even correct, I don't have a clue which one to use so I figured the latest one)</p>
