Log in and Update the Server:

Log in to your Debian 11 VPS via SSH as user root (You can use a superuser account if the root is not available. Our VPSes come with root access included):

ssh root@IP_Address -p Port_number

Don’t forget to replace ‘IP_Address’ and ‘Port_number’ with the actual IP address of your server and the SSH service port. The default SSH port is 22.

Run the following commands to make sure that all installed packages on your Debian 11 VPS are updated to their latest available versions:

apt-get update -y && apt-get upgrade -y

Odoo is written in Python so you will need to install Python and other required dependencies to your server. You can install all of them using the following command:
