Installing Odoo 19 on Debian 13 (Trixie)—the current stable release as of 2026—requires a shift from older methods. Since Debian Trixie follows PEP 668, you can no longer install Python packages globally using pip. You must use a Virtual Environment (venv) to keep the system stable.

Here is the step-by-step guide to a production-ready installation.

1. System Preparation

First, ensure your system is up to date and install the necessary build tools and libraries.

Bash

sudo apt update && sudo apt upgrade -y
sudo apt install -y git wget nodejs npm build-essential python3-dev \
python3-venv python3-pip libxml2-dev libxslt1-dev zlib1g-dev \
libsasl2-dev libldap2-dev libssl-dev libpq-dev libjpeg-dev \
libwebp-dev libtiff-dev libfreetype6-dev liblcms2-dev \
libopenjp2-7-dev libharfbuzz-dev libfribidi-dev libxcb1-dev

2. Install PostgreSQL

Odoo 19 performs best with PostgreSQL 16 or 17, which are standard in the Trixie repositories.

Bash

sudo apt install postgresql -y
sudo systemctl start postgresql && sudo systemctl enable postgresql

# Create a database user for Odoo
sudo su - postgres -c "createuser -s odoo19"

3. Install Wkhtmltopdf

Odoo requires this to generate PDF reports. While Trixie has versions in the repo, it is often safer to grab the generic package if you encounter rendering issues.

Bash

wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6.1-3/wkhtmltox_0.12.6.1-3.bookworm_amd64.deb
sudo apt install ./wkhtmltox_0.12.6.1-3.bookworm_amd64.deb -y

4. Setup Odoo User and Environment

For security, never run Odoo as root. We will create a system user and a virtual environment.

Bash

# Create system user
sudo useradd -m -U -r -d /opt/odoo19 -s /bin/bash odoo19

# Clone Odoo 19 source code
sudo git clone --depth 1 --branch 19.0 https://www.github.com/odoo/odoo /opt/odoo19/odoo

# Create and activate Virtual Environment (PEP 668 compliant)
sudo su - odoo19
python3 -m venv odoo-venv
source odoo-venv/bin/activate

# Install requirements inside the venv
pip install --upgrade pip
pip install -r odoo/requirements.txt
exit

5. Configuration and Service File

Create the configuration file to define your master password and database details.

Create config: sudo nano /etc/odoo19.conf

Ini, TOML

[options]
admin_passwd = your_strong_master_password
db_host = False
db_port = False
db_user = odoo19
db_password = False
xmlrpc_port = 8069
logfile = /var/log/odoo19/odoo19.log
addons_path = /opt/odoo19/odoo/addons

Create Systemd Service: sudo nano /etc/systemd/system/odoo19.service

Code snippet

[Unit]
Description=Odoo19
Requires=postgresql.service
After=network.target postgresql.service

[Service]
Type=simple
SyslogIdentifier=odoo19
PermissionsStartOnly=true
User=odoo19
Group=odoo19
ExecStart=/opt/odoo19/odoo-venv/bin/python3 /opt/odoo19/odoo/odoo-bin -c /etc/odoo19.conf
StandardOutput=journal+console

[Install]
WantedBy=multi-user.target

6. Finalize and Launch

Set permissions and start the service.

Bash

sudo mkdir /var/log/odoo19
sudo chown odoo19: /var/log/odoo19
sudo chown -R odoo19: /opt/odoo19
sudo chmod 640 /etc/odoo19.conf
sudo chown odoo19: /etc/odoo19.conf

sudo systemctl daemon-reload
sudo systemctl enable --now odoo19

7. Accessing Odoo

You can now access your instance at:

http://<your_server_ip>:8069

💡 Troubleshooting Tip for 2026

Since Debian Trixie is a newer environment, ensure that your Node.js version (for RTL and CSS processing) is at least v18+. You can check this with node -v. If Odoo 19 fails to render styles, you may need to install the rtlcss package globally:

sudo npm install -g rtlcss
