Buildozer Gives Error Upon Building Pong App Of Kivy Framework For Android Publishing

I am trying to make an apk file using buildozer of the Pong App (https://kivy.org/doc/stable/tutorials/pong.html) However I am getting the following error on running the buildozer

Solution 1:

So, it looks like Buidozer is having issues finding the sh package. Take a look at https://www.pythonforbeginners.com/modules-in-python/how-to-use-sh-in-python. Dont feel bad, I have had similar experiences with Buildozer.
