How to Setup Free SSL Certificate

Install Let’s Encrypt on Ubuntu 20.04

In this tutorial, we will learn how to Setup SSL Certificate for Apache on Ubuntu 20.04.

Let’s Encrypt is a Certificate Authority (CA), it provides a free valid SSL certificate. To get a free SSL certificate we have to use Certbot Client which fetches and deploys the SSL certificate on our Server.

Before we begin

Always remember that the Let’s Encrypt certificate can only be requested from the server on which the Domain is pointing. Let’s Encrypt checks the Domain is pointing on the same server or not, if the Domain is successfully pointing to the same server then it will install the certificate on the server.

Prerequisites

  • Access of Root User or the access of Another User with sudo privileges.
  • Make sure the Domain is pointing on the same server.
  • Ubuntu 20.04 must be installed on the server.

Install the Certbot Client

To install the SSL certificate on the server follow the below steps.

  • Add the PPA repository on the server to download and install the Certbot Client. If your Linux system already have this repository then it shows some error.
sudo add-apt-repository ppa:certbot/certbot
