On Saturday 19 July 2025, the annual Debian Developers and Contributors Conference came to a close.

Over 443 attendees representing 50 countries from around the world came together for a combined 169 events (including some which took place during the DebCamp) including more than 50 Talks, 39 Short Talks, 5 Discussions, 59 Birds of a Feather sessions ("BoF" – informal meeting between developers and users), 10 workshops, and activities in support of furthering our distribution and free software, learning from our mentors and peers, building our community, and having a bit of fun.

The conference was preceded by the annual DebCamp hacking session held 7 through 13 July where Debian Developers and Contributors convened to focus on their individual Debian-related projects or work in team sprints geared toward in-person collaboration in developing Debian.

This year, a session was dedicated to prepare the BoF "Dealing with Dormant Packages: Ensuring Debian's High Standards"; another, at the initiative of our DPL, to prepare suggestions for the BoF “Package Acceptance in Debian: Challenges and Opportunities"; and an afternoon around Salsa-CI.

As has been the case for several years, a special effort has been made to welcome newcomers and help them become familiar with Debian and DebConf by organizing a sprint "New Contributors Onboarding" every day of Debcamp, followed more informally by mentorship during DebConf.

The actual Debian Developers Conference started on Monday 14 July 2025.

In addition to the traditional "Bits from the DPL" talk, the continuous key-signing party, lightning talks, and the announcement of next year's DebConf26, there were several update sessions shared by internal projects and teams.

Many of the hosted discussion sessions were presented by our technical core teams with the usual and useful "Meet the Technical Committee", the "What's New in the Linux Kernel" session, and a set of BoFs about Debian packaging policy and Debian infrastructure. Thus, more than a quarter of the discussions dealt with this theme, including talks about our tools and Debian's archive processes. Internationalization and Localization have been the subject of several talks. The Python, Perl, Ruby, Go, and Rust programming language teams also shared updates on their work and efforts. Several talks have covered Debian Blends and Debian-derived distributions and other talks addressed the issue of Debian and AI.

More than 17 BoFs and talks about community, diversity, and local outreach highlighted the work of various teams involved in not just the technical but also the social aspect of our community; four women who have made contributions to Debian through their artwork in recent years presented their work.

The one-day session "DebConf 2025 Academic Track!", organized in collaboration with the IRISA laboratory was the first session welcoming fellow academics at DebConf, bringing together around ten presentations.

The schedule was updated each day with planned and ad hoc activities introduced by attendees over the course of the conference. Several traditional activities took place: a job fair, a poetry performance, the traditional Cheese and Wine party (this year with cider as well), the Group Photos, and the Day Trips.

For those who were not able to attend, most of the talks and sessions were broadcasted live and recorded; currently the videos are made available through this link.

Almost all of the sessions facilitated remote participation via IRC and Matrix messaging apps or online collaborative text documents which allowed remote attendees to "be in the room" to ask questions or share comments with the speaker or assembled audience.

DebConf25 saw over 441 T-shirts, 3 day trips, and up to 315 meals planned per day.

All of these events, activities, conversations, and streams coupled with our love, interest, and participation in Debian and F/OSS certainly made this conference an overall success both here in Brest, France and online around the world.

The DebConf25 website will remain active for archival purposes and will continue to offer links to the presentations and videos of talks and events.

Next year, DebConf26 will be held in Santa Fe, Argentina, likely in July. As tradition follows before the next DebConf the local organizers in Argentina will start the conference activities with DebCamp with a particular focus on individual and team work towards improving the distribution.

DebConf is committed to a safe and welcome environment for all participants. See the web page about the Code of Conduct on the DebConf25 website for more details on this.

Debian thanks the commitment of numerous sponsors to support DebConf25, particularly our Platinum Sponsors: AMD, EDF, Infomaniak, Proxmox, and Viridien.

We also wish to thank our Video and Infrastructure teams, the DebConf25 and DebConf committees, our host nation of France, and each and every person who helped contribute to this event and to Debian overall.

Thank you all for your work in helping Debian continue to be "The Universal Operating System".

See you next year!
