Apache Ubuntu 16.04

I'm trying to renew my SSL certificate on apache running on an ubuntu droplet with certbot.
I have followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04

I run sudo certbot renew and I get this message:

Any help is very apreciated. Best regards Kresten
