ImportError: ‘pyOpenSSL’ module missing required functionality.

Apparemment, il y a une friction sur un package python entre le certbot de Let’s encrypt et docker sur CentOS 7.

Donc, si vous rencontrez cette erreur :

[root@server]# certbot renew --dry-run
Traceback (most recent call last):

ImportError: 'pyOpenSSL' module missing required functionality. Try upgrading to v0.14 or newer.

Premièrement, on serait tenté de faire des choses sur le module ssl de python. Mais la solution est toute autre:

[root@server]# pip uninstall urllib3
[root@server]# yum reinstall python-urllib3
[root@server]#certbot renew --dry-run

Et voila, vous retrouverez votre certbot fonctionnel.
