Install SSL certificate on Ubuntu 20.04 using Certbot

-

 

First  you make sure you have a virtual host file for your domain. In my case I have /etc/apache2/sites-available/www.conf 


Step 1 — Installing Certbot

  • $ sudo apt install certbot python3-certbot-apache

  • Step 2 — Allowing HTTPS Through the Firewall
  • $ sudo ufw allow 'Apache Full'
  • $ sudo ufw delete allow 'Apache'

Step 3 — Obtaining an SSL Certificate
