My domain is: 46.101.14.60 linked to subtleradio.live

I ran this command:

  1. SSH into the serverSSH into the server running your HTTP website as a user with sudo privileges.

  2. Add Certbot PPAYou’ll need to add the Certbot PPA to your list of repositories. To do so, run the following commands on the command line on the machine:

  3. sudo apt-get update

  4. sudo apt-get install software-properties-common

  5. sudo add-apt-repository universe

  6. sudo add-apt-repository ppa:certbot/certbot

  7. sudo apt-get update

  8. Install CertbotRun this command on the command line on the machine to install Certbot.

sudo apt-get install certbot python-certbot-nginx

  1. Choose how you’d like to run Certbot
  • Either get and install your certificates…Run this command to get a certificate and have Certbot edit your Nginx configuration automatically to serve it, turning on HTTPS access in a single step.

sudo certbot --nginx

  • Or, just get a certificateIf you’re feeling more conservative and would like to make the changes to your Nginx configuration by hand, run this command.

sudo certbot certonly --nginx

It produced this output:

My web server is (include version): Ubuntu 16.04.4 x64

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is: digital ocean

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): terminal

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):

your server has a lot more issues you should take care of, before thinking about certbot.

for example, you should tell dpkg to reconfigure nginx.
