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

SystemError: ffi_prep_closure(): bad user_data (it seems that the version of
the libffi library seen at runtime is different from the 'ffi.h' file seen at
compile-time)
** Also affects: libffi (Ubuntu)
Importance: Undecided
Status: New
** Summary changed:
- python3-openssl appears to be built against the wrong version of libffi
+ libffi7 missing from Ubuntu (pip's python3-openssl appears to be built
against the wrong version of libffi)
