If you prefer to install Odoo manually or want to understand each step of the process, follow the step-by-step installation guide below.

Step-by-Step Installation Odoo 20 on Ubuntu Guide

Step 1: Update the System

Before installing Odoo 20, update your Ubuntu system to ensure all installed packages are up to date. This helps prevent compatibility issues and ensures you’re working with the latest security updates.

sudo apt update && sudo apt upgrade -y

Once the update is complete, proceed to install the required dependencies.

Step 2: Install Required Dependencies

Odoo requires several system packages, development libraries, and Python tools to install and run correctly. Install all the required dependencies using the following command.

sudo apt install -y git python3-pip python3-venv python3-dev \
build-essential wget curl gcc g++ make \
libxml2-dev libxslt1-dev libzip-dev zlib1g-dev \
libsasl2-dev libldap2-dev libjpeg-dev libpq-dev \
libffi-dev libssl-dev liblcms2-dev \
libblas-dev libatlas-base-dev npm xfonts-75dpi \
xfonts-base fontconfig

Depending on your internet connection, this process may take a few minutes.

Step 3: Install PostgreSQL and Create a PostgreSQL User

PostgreSQL is the default database management system used by Odoo to store application and business data. Install PostgreSQL and its additional utilities by running the following command.

sudo apt install postgresql postgresql-contrib -y

After the installation is complete, verify that the PostgreSQL service is running.

sudo systemctl status postgresql

Create a new PostgreSQL user named odoo20.

sudo -u postgres createuser --createdb --no-createrole --no-superuser odoo20

This user will be used by Odoo to create and manage its databases.

Step 4: Create an Odoo System User

Running Odoo under a dedicated Linux user is a recommended security practice. It keeps application files organized and limits system access.

Create the Odoo system user.

sudo useradd -m -d /opt/odoo -U -r -s /bin/bash odoo20

Step 5: Install wkhtmltopdf

Odoo uses wkhtmltopdf to generate PDF reports such as invoices, quotations, purchase orders, and other printable documents.

Install it using:

sudo apt install wkhtmltopdf -y

After installation, Odoo will be able to generate PDF reports without additional configuration.

Step 6: Download Odoo 20 Source Code

Download the latest Odoo 20 source code from the official GitHub repository.

sudo su - odoo20

Clone Odoo 20 from official GitHub repository:

git clone https://github.com/odoo/odoo --depth 1 --branch 20.0 --single-branch odoo20

This command downloads only the latest branch history, reducing download time and disk usage.

Step 7: Create a Python Virtual Environment

Using a Python virtual environment keeps Odoo’s Python packages isolated from the rest of the operating system. This simplifies dependency management and prevents package conflicts.

Create a virtual environment.

cd /opt/odoo
python3 -m venv venv-20

Activate it.

source venv-20/bin/activate

Step 8: Install Python Dependencies

Upgrade pip and install all the Python packages required by Odoo 20.

cd odoo20
pip install --upgrade pip wheel setuptools
pip install -r requirements.txt

This process may take several minutes depending on your internet connection.

Step 9: Create the Log Directory

Create a directory to store Odoo log files.

sudo mkdir -p /var/log/odoo

Assign the correct ownership.

sudo chown -R odoo20:odoo20 /var/log/odoo

Step 10: Create the Odoo Configuration File

The Odoo configuration file stores important settings such as the database user, addons path, log file location, and other application parameters.

Create the configuration file.

sudo nano /etc/odoo20.conf

Add the following configuration.

[options]
admin_passwd = ChangeThisToAStrongPassword
db_host = False
db_port = False
db_user = odoo20
db_password = False
addons_path = /opt/odoo/odoo20/addons
logfile = /var/log/odoo/odoo20.log

Save the file by pressing Ctrl + O, Enter, and then exit the editor with Ctrl + X.

Note: Replace ChangeThisToAStrongPassword with a strong password of your choice. This password is used to manage Odoo databases (create, restore, duplicate, and delete databases), so do not leave it as the default value.

Optional: Secure the Configuration File

For improved security, restrict access to the Odoo configuration file so that only the Odoo user and group can read it.

sudo chown odoo20:odoo20 /etc/odoo20.conf
sudo chmod 640 /etc/odoo20.conf

This helps protect sensitive configuration settings, such as the database user and the Odoo master password, from unauthorized access.

Step 11: Create the Systemd Service

Creating a Systemd service allows Odoo to start automatically when the server boots and makes it easier to manage.

Create the service file.

sudo nano /etc/systemd/system/odoo20.service

Add the following configuration.

[Unit]
Description=Odoo 20 ERP
After=network.target postgresql.service

[Service]
Type=simple
User=odoo20
Group=odoo20
WorkingDirectory=/opt/odoo/odoo20
ExecStart=/opt/odoo/venv-20/bin/python3 /opt/odoo/odoo20/odoo-bin -c /etc/odoo20.conf
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Save the file by pressing Ctrl + O, Enter, and then exit the editor with Ctrl + X.

Step 12: Reload Systemd

Reload the Systemd daemon so it recognizes the new service.

sudo systemctl daemon-reload

Step 13: Enable and Start the Odoo Service

Enable the Odoo service to start automatically at boot and start it immediately.

sudo systemctl enable --now odoo20.service

Step 14: Verify the Installation

Verify that the Odoo service is running.

sudo systemctl status odoo20.service

If the service status displays active (running), Odoo has been installed successfully.

Step 15: Access Odoo 20

Open your web browser and visit:

http://YOUR_SERVER_IP:8069

The Odoo database setup page will appear. Create your first database to begin using Odoo 20.

To monitor Odoo logs in real time for troubleshooting or activity monitoring, run:

tail -f /var/log/odoo/odoo20.log
