Tryton Debian Apt Repository


Due to the different release schemata and policies of Tryton and Debian it is currently impossible to make all Tryton releases available for the different Debian suites in the main repository of Debian.

Our intention is to make available Tryton releases including their bug fix releases via this aptable package mirror.

By using this mirror

  • you can run the Tryton release of your choice on your current stable or testing Debian system (oldstable supported as long as possible).

  • you are able to upgrade to the next Tryton series as soon as you wish to do so.

  • you are independent from the next Tryton major entering in Debian main.

  • you get all bug fix releases for all supported Tryton series.


This service depends on sponsoring, a full list of current and former supporters can be found on the Tryton Debian Supporters page.

Please note that the current ressources allow for:
  • Packaging of Tryton LTS series with inclusion in Debian main

  • Immediate packaging of Tryton security releases depending on their impact

  • Packaging of the first 4 Tryton (LTS) bugfix releases after the release

  • Packaging of Tryton bugfix releases for the supported series in a quarterly rhythm (i.e. all 3 months)

If you want to help or if you need to get more Tryton series, more releases or specific packages maintained you are very welcome to get in touch with the maintainers.

How To

To use this package mirror with the apt package mangement of your Debian system you must make available the according sources.list to your system. The following steps have to be performed:

  • Import the signing key of the mirror.

  • Import the suitable sources.list for your target Debian release and Tryton series.

  • Tell the system to take Tryton related packages preferrably from this mirror.

Please read below for further instructions on how to do that.

For the installation of GNU Health you find additional instructions at GNU Health Debian Apt Repository.

For the server configuration please refer to /usr/share/doc/tryton-server/README.Debian on your Debian system or look at the latest version of README.Debian in the VCS.

Supported Distributions

Naming convention for distributions is <Debian-Release>-<Tryton-Version>

e.g. buster-5.0, bullseye-6.0

Packages suitable for testing and unstable are available under the distribution <Debian-Future-Release>-<Tryton-Version>

e.g. at the time of writing bookworm-6.0

All available distributions can be found at Debian Tryton Distributions.

Mirror Key and Sources

First it is required to add the signature key of this mirror to apt

$ sudo curl -o /etc/apt/trusted.gpg.d/

Adding the sources to apt basically works like

$ echo "deb <distribution> main" | sudo tee -a /etc/apt/sources.list

The following chapter provides ready-to-use examples for the ditribution and series of your choice.


The following examples show the download of ready-to-use source list files. They can be downloaded and saved directly to /etc/apt/sources.list.d by running the command of your target distribution and series

Distribution buster-5.0

$ FILE=tryton-buster-5.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE

Distribution buster-6.0

$ FILE=tryton-buster-6.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE

Distribution bullseye-5.0

$ FILE=tryton-bullseye-5.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE

Distribution bullseye-6.0

$ FILE=tryton-bullseye-6.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE

Distribution bookworm-5.0

$ FILE=tryton-bookworm-5.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE

Distribution bookworm-6.0

$ FILE=tryton-bookworm-6.0.list; sudo curl -o /etc/apt/sources.list.d/$FILE$FILE


Update the package lists

$ sudo apt update

Choose between the following options for your use case:

Install just the server

$ sudo apt install tryton-server [-t <distribution>]

Install all modules incl. server

$ sudo apt install tryton-modules-all [-t <distribution>]

Install a complete production ready Tryton server environment including the guided setup of a wsgi backend (uWSGI), a web frontend (nginx) with optionally setup of secure access via https with Letsencrypt certificates

$ sudo apt install tryton-server-all-in-one [-t <distribution>]

Install the client to access the server from your local or remote machine

$ sudo apt install tryton-client [-t <distribution>]


The versioning of Tryton packages from is conservative with respect to upgrades. It follows the ususal backports schema to provide upgradibility to a new Debian release at every moment. Therefore it may be, that apt will want to replace the installed version with a newer version number, that is evtl. available from other (or the default) sources.lists.

To stick with the packages of, it is favorable to pin the packages. With pin priority >1000 they will always be preferred over other packages. A sample looks like

Package: *
Pin: release
Pin-Priority: 999

A suitable file can be downloaded with

$ sudo curl -o /etc/apt/preferences.d/

Use the new preferences with

$ sudo apt update && apt dist-upgrade
