compatiblity. LP: #1903890

I have now shipped libffi7 in hirsute. Such that if one installs third-party
binaries, on hirsute, one can install libffi7 from the archive, and things
should "just work". It would be nice if somebody who is affected could verify
that.
You can get hirsute trivially with lxd.
Or please provide concrete reproducer examples - i.e. specifically which
applications, downloaded from where, and installed how would be useful.
I see a few things mentioned in this bug report, but not detailed enough
for me to experience the issue myself.

libffi7 missing from Ubuntu (pip's python3-openssl appears to be built
against the wrong version of libffi)

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):
