I see a few issues: * First of all, you need to convert some - to _ since these are translated into python modules * Then, does that suffice? Looking into the conf files I have, I also see lines authenticator = dns-gandi coming from the calls OLD: certbot certonly --certbot-plugin-gandi:dns-credential /etc/letsencrypt/gandi.ini -d DOMAIN_LIST NEW: certbot certonly --authenticator dns-gandi --dns-gandi-credentials /etc/letsencrypt/gandi.ini -d DOMAIN_LIST Now with the above you would rewrite the config file lines certbot-plugin-gandi:dns_credentials = ... to dns_gandi_credentials = ... (Note the _ here for dns_gandi_credentials and most probably also for dns_credentials, but I cannot check now!) But then still the new line authenticator = dns-gandi is missing. Just as food for thoughts.
