# Script for installing Odoo on Ubuntu 20.04, 22.04 and 24.04 (could be used for other version too with adjustments)
# Author: Yenthe Van Ginneken
#-------------------------------------------------------------------------------
# This script will install Odoo on your Ubuntu server. It can install multiple Odoo instances
# in one Ubuntu because of the different http_ports
#-------------------------------------------------------------------------------
# Make a new file:
# sudo nano odoo_install.sh
# Place this content in it and then make the file executable:
# sudo chmod +x odoo_install.sh
# Execute the script to install Odoo:
# ./odoo-install
