Buildozer error while compiling apk - pip ssl

Question

I am trying to compile a simple program into an apk for Android with Buildozer but have run into the following problem. Can you please help? I tried upgrading pip but that didn't help:python3 -m pip install --upgrade pip

So, I reverted back to the original pip version.

Installed Cython separately: pip3 install Cython

But the same issue persists. I am at a loss. :-(

Command: buildozer android debug

RAN: /bin/bash -c 'venv/bin/pip install Cython'
STDOUT:
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

How can I fix this?

Could not fetch URL https://pypi.org/simple/cython/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/cython/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

This is a recent bug, you need to install libssl-dev using apt install libssl-dev

Then you might also want to clean your buildozer directory by running rm -rf .buildozer in the directory that contains your buildozer.spec file.

That should do it!
