No effect?? certbot revoke --cert-path /etc/letsencrypt/live/MyDomain/fullchain.pem produced “Congratulations! You have successfully revoked the certificate that was located
at …”, but it is confuse, no “deletion”, all is there when I check again by certbot certificates.
I need a real “delete”, to purge old certificates that are listed in certbot certificates… not see here an instruction and objective “step-by-step” how-to for it.
