Hello,
I am in the process of building a brand new Debian server running 8.5.0 amd64. During installation of the OS for installation options I selected Web server, SSH server and standard system utilities.
After that base was installed I proceeded to go to https://certbot.eff.org/#debianjessie-apache to follow the directions. I added the jessie-backports to my sources ran the apt-get install as specified after an update.
Installation proceeds without error but when I try to run certbot --apache I get the following error:
root@DEN:/usr/lib# certbot --apache
Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'cffi>=1.4.1' distribution was not found and is required by cryptography
Running pydoc modules shows _cffi_backend as available.
I suspect there is some missing package or dependency but I haven’t been able to identify it so I thought I would reach out in the hopes someone else can provide some clarity into what I’m missing or ideas on how to proceed.
Thanks in advance,
