Installing Certbot breaks Apache on Ubuntu servers

Symptoms

After installing the certbot package, web pages show the default cPanel page, and the httpd service will not start.

Description

The certbot package installs the apache2 package and runs the apache2 service in place of the cPanel-provided httpd service.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Remove the conflicting packages.

   apt-get remove apache2 apache2-utils apache2-data certbot python3-certbot python3-certbot-apache -y

3. Reinstall the ea-apache24 package.

   apt reinstall ea-apache24 -y
