Best Method for Odoo 19 Installation on Ubuntu

If you are a developer, system admin, or just starting with Odoo, follow this installation guide to run Odoo 19 in your environment.

Prerequisites

Make sure your Ubuntu system meets the following requirements before starting the installation:

• Ubuntu 20.04 or 22.04 (64-bit recommended)
• Root or sudo user access
• PostgreSQL 14+
• Python 3.10+

Step-by-Step Installation Guide

1. Update Ubuntu System

Before starting any installation, make sure your system is updated with latest packages.

sudo apt update && sudo apt upgrade -y

This will help avoid issues later with compatibility or missing libraries.

2. Install Required Packages and Dependencies

Odoo needs some system libraries and Python packages. Run below command:

sudo apt install build-essential wget git python3-pip python3-dev python3-venv python3-wheel \
libfreetype6-dev libxml2-dev libzip-dev libsasl2-dev python3-setuptools libjpeg-dev zlib1g-dev \
libpq-dev libxslt1-dev libldap2-dev libtiff5-dev libopenjp2-7-dev

3. Install and Configure PostgreSQL

Odoo works with PostgreSQL as database.

sudo apt install postgresql -y
sudo -u postgres createuser --createdb --no-superuser --no-createrole odoo19

This creates a new PostgreSQL user for Odoo 19.

4. Create Odoo User

To run Odoo safely, create a new system user:

sudo adduser --system --home=/opt/odoo --group --shell=/bin/bash odoo19

This user will own and run Odoo application.

5. Install Wkhtmltopdf

This tool helps to generate PDF reports from Odoo.

sudo apt install wkhtmltopdf

Make sure version is correct (wkhtmltopdf 0.12.6). Wkhtmltopdf is very important for printing reports.

6. Download Odoo 19 Source Code

Switch to Odoo user:

sudo su - odoo19

Clone Odoo 19 from official GitHub:

git clone https://github.com/odoo/odoo --depth 1 --branch 19.0 --single-branch odoo19

cd /opt/odoo
python3 -m venv venv-19

cd odoo19
pip install wheel
pip install -r requirements.txt

deactivate 

This will install all required Python packages.

8. Create Log Directory

sudo mkdir /var/log/odoo
sudo chown odoo19:odoo19 /var/log/odoo

8. Create Odoo Configuration File

db_host = False
db_port = False
db_user = odoo19
db_password = False
addons_path = /opt/odoo/odoo19/addons
logfile = /var/log/odoo/odoo19.log
