Hello!

This error comes up when I try to use certbot-auto with apache : certbot.renewal:Renewal configuration file /etc/letsencrypt/renewal/…conf produced an unexpected error: ‘Namespace’ object has no attribute ‘standalone\_supported\_challenges’. Skipping.

Any sugggestion would be greatly appreciated
