How to install CertBot

Certbot is an SSL installer tool that works with letsencrypt and supports nginx and apache. It works on many systems but this guide will only contain how to use it for debian based systems.

Method 1: Using snapd

This is the recommened way of installing certbot (application) by certbot (application developers). Although, Avoiding snapd should be considered in general applications. It does install certbot with all the plugins you may require which can be an advantage.

1. Update your package repositories.(Only do this if snapd is not installed) Syntax:

apt update && apt upgrade -y

2. Install snapd. (Only required if snapd is not already installed.) Syntax:

apt install snapd -y

3. Install certbot. Syntax:

snap install --classic certbot

4. Set snapd binary. Syntax:

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

Method 2: Using apt

Prefering to use apt would always be the recommended way to install software even though it might be behind few versions/not always the latest release of the software. Even though certbot developers don't recommend this way of installation, It can be considered the "better way" to install the software.

1. Update your package repositories & install software-properties package. Syntax:

apt install software-properties-common && apt update && apt upgrade -y

2. Install certbot. Syntax:

apt install certbot

4. Install nginx plugin. Syntax:

apt install python-certbot-nginx

5. Install apache plugin. Syntax:

apt install python-certbot-apache
