** Description changed: + Ubuntu groovy and up upgraded to libffi8ubuntu1, thus making Ubuntu + incompatible with 3rd-party binaries that desire to use libffi7. + + Let's backport and provide libffi7 runtime library only, for those. + + Not sure how that would work with ctypes though. + + + --- + I've just upgraded to Ubuntu 20.10 which comes with python3-openssl version 19.0.1-2. It breaks (at least some) Python applications that use the `requests` library to access HTTPS URLS.
