Updated October 2026 to reflect current versions.
Odoo is a powerful, open-source business management software that has become a popular choice for businesses of all sizes. With its intuitive user interface and robust features, Odoo can help streamline your operations and increase productivity. In this guide, we will show you how to install Odoo 20 on Linux systems.
Version note: this guide was originally written for Odoo 16 and refreshed in October 2026 for Odoo 20, the current major release (the page title and URL keep their original name for continuity). What changed between Odoo 16 and Odoo 20 for this install: the minimum Python version went from the 3.10 era to Python 3.12+, the minimum PostgreSQL version went from 12 to PostgreSQL 16+, and wkhtmltopdf (still needed for PDF reports, version 0.12.6) must be installed manually as it is not on PyPI. Odoo 20 also offers AI features that require the pgvector PostgreSQL extension.
