I have a plumber API deployed on Digital Ocean with
plumberDeploy. I have a domain name and want to configure https with
plumberDeploy::do_configure_https(). But I'm getting the error
The repository 'http://ppa.launchpad.net/certbot/certbot/ubuntu focal Release' does not have a Release file.
My DO server is running Ubuntu 20.04 (Focal Fossa). At http://ppa.launchpad.net/certbot/certbot/ubuntu, Focal Fossa isn't there. Hence, that's what I think the error is.
What can I do to resolve this?
