Prerequisites:

• ssh access to the machine running the httpd server

snapd Installation

Remove certbot-auto and any Certbot OS packages. If there are any Certbot packages installed with an OS package manager like apt, dnf, or yum, they should be removed before installing the Certbot snap to ensure that when you run the command certbot the snap is used rather than the installation from your OS package manager:

yum remove certbot

Install certbot with snap. As root:

snap install --classic certbot
