@techpad Before posting huge logs, there looks to be a problem with the command you used. You show certbot-auto but that was deprecated in favor of just certbot. This was primarily due to it needing python2.
Yet, your initial log showed a snap install of certbot with python3. This is the "modern" install. And, you noted certbot version 1.20 which is recent. I do not understand the migration of that older install method well but Rudy and others will be better able to help sort this out. Let's see what they have to say.
Here is a post about that from Dec 2020:
And, the current install page that mentions it too:
