Hi @fede18_lfc,

As per this thread, for example

you most likely need to update to a newer version of Certbot.

The installation instructions for Certbot on Ubuntu 18.04 now recommend using the PPA:

https://certbot.eff.org/lets-encrypt/ubuntubionic-apache

This will allow you to get more recent Certbot releases than the one packaged with your operating system. (Have you updated your OS packages with apt already? Perhaps your operating system itself already has a newer version available.)
