Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: my self
I can login to a root shell on my machine (yes or no, or I don't know): yes i have pure root uid 0
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no cpanel
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): latest (new install from ubuntu 22.04 repos)
I need to delete / revoke my certificates so i can regenerate them for my mail and other servers to include the automatic renewal.
Unless you lost control of the corresponding secret key, there is no need to revoke a certificate.
"Latest" is a moving target and not a useful version descriptor. Real numbers are required to impart any relevant meaning. You should use the snap version on Ubuntu to ensure that you stay up to date. Packaged versions in distribution repositories tend to get stale rather quickly.
If you only need to add or change domains, you can so that eight from the command line.
Hey @cryptodanvr Welcome to the forum.
Unless you have some special reason to, there is really no need to revoke the certs. You can just let them expire gracefully.
Just get a new cert with the relevant domain/host names and you'll be good to go.
The reason I want to revoke to create again is to have all my mail certs for pop3 and imap under one cert for my Postfix/Dovecot instances and all my chat/collaboration certs under one separate cert.
Revoking doesn't change what certs Let's Encrypt will issue
We can help you with the needed options for expanding, contracting, and deleting Certbot cert profiles. But, it would be helpful then to see the other answers to the form you chose not to answer.
