I am glad that this worked out fine now.
I am not sure there is time to fix this in 20.10, as it has only a few
months of support left. I hope that having libffi7 in 21.04 is enough.

Bug description:
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. For instance, this
stack trace (note that I have clipped the first few frames from the
stack as they are proprietary):
