Package: certbot
Version: 0.10.2-1
Severity: important

Trying to run certbot on a fresh install on my Stretch box leads me to the
following stackdump:

I've tried manually installing python3-cffi and python-cffi, without luck.
Therefore the package is useless for me. I really have no clue on what to try
next.
