Question

Python

Good afternoon.
I'm using Ubuntu 16.04
I had to remove the mentioned module because there was an error installing the python module. Now this error appears when using buildozer. It is not possible to install python 3.5, because when it is removed, the OS is also removed. How can I add this module
Good day
