Due to some conflicting installations of third-parties software in my Ubuntu 18.04.01 Server Edition I need to wipe everything out and reinstall Ubuntu again (no network connection anymore)
What are the files and the folders which must be saved and can be copied later on in order to avoid to pass through the entire lengthy certification process?
I suggest backing up the entire /etc/letsencrypt folder if you’re using certbot as a client. If you’re using another client, I’d recommend checking where that client leaves it’s configuration files and certificates/private keys.
So. Everything related to certbot’s certifications is packed within /etc/letsencrypt folder…And it should be a matter of just copying this folder into the new installed Ubuntu. Is it right?
