Just need to run sudo certbot --apache again and there is the option to renew. One of my original fears about free certs was that they had to be renewed so often. But if that is all it takes then "no problamo". 👍

Very cool

It took me 3hrs but at least I now know how to do it. Had to move to my Mint box, install apache2 and php and then certbox apache plugin and certbox and run sudo certbox --apache. Now my site is https and no longer says "unsafe". Thanks for the letsencrypt site.
