    Maybe try upgrading to python3.7 and apt install libffi-dev

    Older versions of pip do not recognize abi3 wheels and try to build from the source package. That often fails when you don’t have the compiler toolchain and build dependencies installed. The simple fix is to upgrade pip so it can pick up the correct wheels. Best to update cffi and setuptools too, as the argon2-cffi manual says:

    pip3 install --user -U cffi setuptools pip

    This module does have wheels for Python 3.6 and 3.7, but you shouldn’t stick to those EOL versions, because many other dependencies have dropped support.
