How to Install Certbot on Ubuntu Linux

Install Certbot via Ubuntu repositories

Installing 💿 Certbot via Ubuntu repositories lets you get the tool using the built-in apt package manager without adding extra software sources. Open your terminal and run sudo apt install certbot to download and set up the program on your system. This method is straightforward, but keep in mind that the version from the official repositories might be older than the release available directly from the developers.

If you prefer using the Ubuntu repositories, follow these steps. Keep in mind, the version installed here might not be the absolute latest.

sudo apt install certbot

Run the commands below to check the installed version or remove the package entirely.

certbot --version

To uninstall Certbot, run the commands below.

sudo apt purge certbot && sudo apt autoremove

Install Certbot via the Snap package manager

Installing Certbot via the Snap package manager gives you the newest version of the tool along with all its required parts in one neat package. Open your terminal and run sudo snap install --classic certbot to set it up on your computer. This approach is often better than older methods because Snap (a universal package manager designed for Linux) handles updates automatically in the background.

Another method for installing Certbot is by using Snap.

Canonical's Snap (a universal package manager designed to bundle software and dependencies together) handles updates seamlessly across different Linux distributions.

To install Certbot via Snap, run the command below.

sudo snap install --classic certbot

After installing, create a symbolic link from the Certbot Snap location /snap/bin/certbot to /usr/bin/certbot. This makes running Certbot commands more convenient.

Run the command below to create that link:

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

Now, check the installed version.

certbot --version 

With Certbot installed, you can automatically create and renew certificates from the Let's Encrypt Certificate Authority.

First, start with a test certificate to ensure your web server configuration is correct before proceeding with an actual valid certificate.

To install a test certificate for a Nginx web server, run the command below.

sudo certbot --nginx --test-cert

Run the command below to get a valid certificate if the test succeeds.

sudo certbot --nginx
