Comment 1 James Hogarth 2016-07-19 13:57:23 UTC
Did a quick test and I cannot reproduce in a fresh C7 install with stable or testing certbot packages

Probably a bad pip clash?

Comment 2 Pierre-YvesChibon 2016-07-19 16:24:12 UTC
It was likely a messed-up with pip.

I yum remove python-cryptography, since there were some files left I rm'ed them and reinstall certbot (which brought python-cryptography w/ it) after that it worked fine.

Thanks and sorry for the troubles!
