At least for Ubuntu 20.04, Letsencrypt does not require you to install the Python stack for certbot anymore and switched to a Snapd package. Although at least I had to install Snapd for that matter.
I use acme.sh with dns, it just plonks a certificate in a directory of your choice and runs a reload command of your choice. I actually upload the certificate into a kubernetes cluster. All repeated by cron
Tried doing the same with a Ubuntu 14.04 server. That failed totally while installing snapd on it, which replaced existing upstart init system with systemd. This caused no services to start on next reboot.

To be clear: the snap is available and maintained by upstream. If you want the latest version of Certbot directly from upstream then the snap is the easiest way to get it. However Ubuntu 20.04 itself also ships the deb as packaged so you can use that if you want, and the "pip install" method in a virtualenv also works (but IMHO is the least maintainable method; it's more useful as a building block for other mechanisms).
