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

  You’ll need to install snapd and make sure you follow any instructions to enable classic snap support.

  Follow these instructions on snapcraft’s site to install snapd.

  install snapd

• Ensure that your version of snapd is up to date

  Execute the following instructions on the command line on the machine to ensure

  that you have the latest version of snapd.

  sudo snap install core; sudo snap refresh core

• Remove certbot-auto and 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.

  If you previously used Certbot through the certbot-auto script, you should

  also remove its installation by following the instructions here.

• Install Certbot

  Run this command on the command line on the machine to install Certbot.

  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:

  • /etc/crontab/
  • /etc/cron.*/*
  • systemctl list-timers
• Confirm that Certbot worked
