How do I install Certbot now?

The way we recommend most users install Certbot is through snaps. You can find instructions for doing this at https://certbot.eff.org/instructions.

On Ubuntu 16.04

$ sudo snap install core; sudo snap refresh core

Remove any Certbot OS packages

If you have any Certbot packages installed using an OS package manager like apt, dnf, or yum, you should remove them before installing the Certbot snap to ensure that when you run the command certbot the snap is used rather than the installation from your OS package manager. The exact command to do this depends on your OS, but common examples are sudo apt-get remove certbot, sudo dnf remove certbot, or sudo yum remove certbot.

$ apt-get remove certbot
$ apt autoremove

Install Cerbot

$ sudo snap install --classic certbot

Prepare the Certbot command

Execute the following instruction on the command line on the machine to ensure that the certbot command can be run.

$ sudo ln -s /snap/bin/certbot /usr/bin/certbot

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 Apache configuration automatically to serve it, turning on HTTPS access in a single step.

$ sudo certbot --apache

Or, just get a certificate

If you’re feeling more conservative and would like to make the changes to your Apache configuration by hand, run this command.

$ sudo certbot certonly --apache

Test automatic renewal

The Certbot packages on your system come with a cron job or systemd timer that will renew your certificates automatically before they expire. You will not need to run Certbot again, unless you change your configuration. You can test automatic renewal for your certificates by running this command:

$ sudo certbot renew --dry-run

The command to renew certbot is installed in one of the following locations:

systemctl list-timers
