How to Install a Free SSL Certificate on Ubuntu

First of all, you need to get a certificate for your Ubuntu server.

I am using Apache as my webserver.

We’re going to use the free certificate provider letsencrypt.

I recommend that you install the packages from the PPA because they are more up to date.

Go to this link:

https://launchpad.net/~certbot/+archive/ubuntu/certbot

And follow the instructions.

This is what you should do:

add-apt-repository ppa:certbot/certbot
apt-get update
apt-get install python-certbot-apache

Then install the certificate for your domain

certbot --apache -d domain.com,www.domain.com
To list all the certificate that you have on your server use this command
certbot certificates
The files should be located in this folder
/etc/letsencrypt/live
If you need to upgrade the certbot ppa, then use this command
apt-get install --only-upgrade certbot
