Hi, I have previously issued a certificate for my domain, say it is domain.de. Now I want to extend it with an SAN for www.domain.de. Hence I just run ./letsencrypt-auto certonly --webroot -w /var/www/letsencrypt/ -d domain.de -d www.domain.de. When I run the tool, the client asks me whether I want to extend the given certificate, and I answer with expand. After some seconds, the following message occurs:
Do you want to expand and replace this existing certificate with the new
certificate?

An unexpected error occurred:
ValueError: max() arg is an empty sequence
Please see the logfiles in /var/log/letsencrypt for more details.
The error log shows the following Python exception:

If required, I can also post the full log. Thanks for helping!
