First you’ll need to install the Let’s Encrypt certbot
sudo apt-get install certbot
Now, we can create a certificate for all of the domains setup within Apache
sudo certbot --apache
Finally, let’s restart Apache!
sudo service apache2 reload
While trying to install the cert I had a few errors relating to “cert authority failed….”
This was overcome by running the following command instead of sudo certbot –apache
sudo certbot --authenticator webroot --installer apache
