I’ve been having a really hard time trying to install a simple SSL certificate on my DigitalOcean virtual server running Ubuntu 18 & Apache2. The certificate was purchased for $10 through and I think most of the frustration is coming from the fact that they issued me a .pem file instead of the .crt and .key files like which are used in essentially all of the tutorials on the subject (I’m sure that the .pem file would work, I just can’t figure out how to do it exactly). This has all been quite the headache here over the past two days. However, I think I may have found a solution!

It seems that there’s actually an organization called Let’s Encrypt that issues free SSL certificates. And the Electronic Frontier Foundation has apparently released a simple tool called Certbot that then automates the installation of these free SSL certificates issued by Let’s Encrypt. Pretty awesome right? So, I think I’m just going to forget about my $10 SSL certificate from, and just try setting everything up using Let’s Encrypt & Certbot instead.

NOTE: Remember to remove your CNAME record from your DNS records for your old SSL certificate, so you can re-do everything using the free SSL cert from Let’s Encrypt.
