The 35th annual conference on Astronomical Data Analysis Software & Systems 2025 in Görlitz, Germany

Debian Astro is a Debian Pure Blend dedicated to astronomy and astrophysics, providing a curated collection of software for observational and theoretical research, data analysis, and education. By integrating widely used packages—ranging from telescope and instrument control to data reduction pipelines and visualization tools—Debian Astro offers researchers a robust, reproducible, and fully open-source environment. The upcoming Debian 13 “Trixie” release continues to expand and modernize this ecosystem with improved packaging, dependency management, and long-term support. It ensures that astronomy software remains accessible, stable, and easy to deploy across platforms. This poster presents the current status of Debian Astro in Trixie, highlights new and updated packages, and outlines the community-driven development process that supports both upstream projects and end users. We also discuss opportunities for collaboration within the astronomical software community to further strengthen open science through Debian Astro.
