Let's Encrypt SSL
Now we need to install Let's Encrypt, this is a way to get a free SSL Certificate for our Ticaga installation.
This allows you to use https://ubuntu.ticaga.com instead of http://ubuntu.ticaga.com.
sudo apt install certbot python3-certbot-apache -y
certbot --apache
If you're using Nginx you will need to change --apache to --nginx. We recommend Apache as it's easier to maintain.
