This is a clean stable 20.04 install of the Raspberry PI image.

$ sudo apt update

E: The repository 'http://ppa.launchpad.net/certbot/certbot/ubuntu focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I would expect that this PPA should either not be included in the default image, or that the Release file should be there. I suspect that this is a stripped-down Ubuntu server image, and that the PPA should not be included in the image.

But which, or another option?

At the time of this post, the Certbot PPA does not have Focal builds currently because the latest Certbot is already in the repositories for 20.04 so the PPA isn't needed for 20.04.

Why the RPi image has that PPA included is a mystery to me, but it's not needed currently for 20.04.
