====== Install the Letsencypt certbot tool on Ubuntu Server 22.04 ======

Install this certbot tool and make the letsencrypt folder path architecture before seting up Apache2 Virtual Host for domains.

At this point, install the certbot tool and thereafter generate the SSL certificates for the Nextcloud installation. 

We will be able to generate SSL Letsencrypts with the webroot plugin.

Run the following command to install the certbot tool for generating SSL Letsencrypt.

<code>
sudo apt install certbot
</code>

Type 'y' and press 'Enter' to continue the installation.

After the installation is complete, create a new directory for letsencrypt authorization using the following commands.

<code>
sudo mkdir -p /var/lib/letsencrypt/.well-known
sudo chgrp www-data /var/lib/letsencrypt
sudo chmod g+s /var/lib/letsencrypt
</code>

Before requesting a certificate from LetsEncrypt, first ensure that an apache2 virtual host domain file has been propertly created and that it's symlink is enabled.
