Question
certbot renew --> AttributeError: module 'lib' has no attribute 'Cryptography_HAS_SSL_ST'

Hi, I’m trying to renew my SSL certificate on apache running on an ubuntu droplet with certbot. I have followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04
I run sudo certbot renew and I get this message:
root@DagensSalg:~# sudo certbot renew Traceback (most recent call last): File “/usr/local/bin/certbot”, line 7, in <module> from certbot.main import main File “/usr/local/lib/python3.5/dist-packages/certbot/main.py”, line 9, in <module> from acme import jose File “/usr/local/lib/python3.5/dist-packages/acme/jose/init.py”, line 37, in <module> from acme.jose.interfaces import JSONDeSerializable File “/usr/local/lib/python3.5/dist-packages/acme/jose/interfaces.py”, line 9, in <module> from acme.jose import util File “/usr/local/lib/python3.5/dist-packages/acme/jose/util.py”, line 5, in <module> import OpenSSL File “/usr/local/lib/python3.5/dist-packages/OpenSSL/init.py”, line 8, in <module> from OpenSSL import crypto, SSL File “/usr/local/lib/python3.5/dist-packages/OpenSSL/SSL.py”, line 115, in <module> if _lib.Cryptography_HAS_SSL_ST: AttributeError: module ‘lib’ has no attribute ‘Cryptography_HAS_SSL_ST’
Any help is very apreciated. Best regards Kresten

Hello,
I had a similar problem in the past and the following fixed the problem for me:
Make sure that this file:
/usr/local/lib/python3.5/dist-packages/OpenSSL/SSL.pywas removed.Then install the package again:
Of course, as always make sure to backup your droplet before making any changes!
Hope that this helps! Regards, Bobby
