Error while using DuckDNS plugin

[sashanknjs]

(sage-env) sage@sage:~/sage $ sudo certbot certonly \
  --non-interactive \
  --agree-tos \
  --email [email protected] \
  --preferred-challenges dns \
  --authenticator dns-duckdns \
  --dns-duckdns-credentials </home/sage/sage/duckdns.ini> \
  --dns-duckdns-propagation-seconds 60 \
  -d "sageai.duckdns.org"

I get the following error when I try to run the above code

usage:
certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

Certbot can obtain and install HTTPS/TLS/SSL certificates. By default,
it will attempt to use a webserver both for obtaining and installing the
certificate.
certbot: error: unrecognized arguments: --dns-duckdns-credentials 60

Did you used the path </home/sage/sage/duckdns.ini> as argument or is this a anonymization of the real path?

The example

--dns-duckdns-credentials </path/to/your/duckdns.ini>

from the Readme have to be adjusted such that the real path replaces the whole substring </path/to/your/duckdns.ini> with the correct path. In your case it would be:

 --dns-duckdns-credentials /home/sage/sage/duckdns.ini

If this doesn't fix the problem, can you provide some more information about your and system:

1. What are the outputs of the commands? certbot plugins and sudo certbot plugins
2. How do you installed the plugin and certbot?
3. What version of certbot_dns_duckdns and certbot are installed? You can use the commands pip show certbot_dns_duckdns and certbot --version
4. What OS are you using?
