  <p>I'm over Ubuntu 16.04, I have done all the steps from here <a href="https://facebook.github.io/react-native/docs/signed-apk-android.html" rel="noreferrer">https://facebook.github.io/react-native/docs/signed-apk-android.html</a> until the testing step where I have to do <code>react-native run-android --variant=release</code></p>
  
  <p>What could it be? :/
  Thanks</p>
