Requirements

To install Pontoon, you will need:

• Debian or Ubuntu with systemd and an administrator (root) access,

• Python with venv module,

• A C / C++ compiler (required to install some of the Python dependencies),

• PostgreSQL

• Git

• And optionally the clients for other VCS you want to use (Mercurial, SVN)

You will find the supported versions synthesized in the table below:

Distribution	Python	PostgreSQL	Distribution End of Support
Debian 10 (buster)	3.7	11	→ 2024-06
Debian 11 (bullseye)	3.9	13	→ 2026-06
Ubuntu 18.04 LTS (bionic)	3.7	10	→ 2023-04
Ubuntu 20.04 LTS (focal)	3.8	12	→ 2025-04

Important

Ubuntu 22.04 LTS (jammy) is not supported yet: Pontoon does not work with Python 3.10 (see #2493).

Note

Please note that the “end of support” date is the end of the Linux distribution support, not the date until when Pontoon will be maintained on this system: if Pontoon’s developers stop supporting Python or PostgreSQL versions available on those platforms, the support will be dropped for newer releases.
