DebConf25, the 25th annual Debian Developer Conference, is taking place in Brest, France from 14 to 19 July 2025. Debian contributors from all over the world have come together at the Campus of IMT Atlantique Bretagne-Pays de la Loire, Brest, to participate and work in a conference exclusively ran by volunteers.

As the conference begins on July 14, the French National Day, Debian can make France's motto its own: "Liberté, égalité, fraternité", Freedom for Free and Open Source Software, Equity for the equal right (and duties) of everyone to use, modify and share Free Software, Fraternity which perfectly covers what our code of conduct defines.

Today the main conference starts with around 500 expected attendants and over 140 scheduled activities, including 45-minute and 20-minute talks, Bird of a Feather ("BoF") team meetings, workshops, a job fair, as well as a variety of other events. The full schedule is updated each day, including activities planned ad-hoc by attendees over the course of the conference.

If you would like to engage remotely, you can follow the video streams available from the DebConf25 website for the events happening in the three talk rooms: Méridienne, Grand amphi and Petit amphi accessible from the DebConf25 homepage. Or you can join the conversations happening inside the talk rooms via the OFTC IRC network in the #debconf-meridienne, #debconf-grandamphi, #debconf-petitamphi, and #debconf-bof channels. Please also join us in the #debconf channel for common discussions related to DebConf.

Dear Debian community,

This is bits from the DPL for June.

The Challenge of Mentoring Newcomers

In June there was an extended discussion about the ongoing challenges around mentoring newcomers in Debian. As many of you know, this is a topic I’ve cared about deeply--long before becoming DPL. In my view, the issue isn’t just a matter of lacking tools or needing to “try harder” to attract contributors. Anyone who followed the discussion will likely agree that it’s more complex than that.

I sometimes wonder whether Debian’s success contributes to the problem. From the outside, things may appear to “just work”, which can lead to the impression: “Debian is doing fine without me--they clearly have everything under control.” But that overlooks how much volunteer effort it takes to keep the project running smoothly.

We should make it clearer that help is always needed--not only in packaging, but also in writing technical documentation, designing web pages, reaching out to upstreams about license issues, finding sponsors, or organising events. (Speaking from experience, I would have appreciated help in patiently explaining Free Software benefits to upstream authors.) Sometimes we think too narrowly about what newcomers can do, and also about which tasks could be offloaded from overcommitted contributors.

In fact, one of the most valuable things a newcomer can contribute is better documentation. Those of us who’ve been around for years may be too used to how things work--or make assumptions about what others already know. A person who just joined the project is often in the best position to document what’s confusing, what’s missing, and what they wish they had known sooner.

In that sense, the recent "random new contributor’s experience" posts might be a useful starting point for further reflection. I think we can learn a lot from positive user stories, like this recent experience of a newcomer adopting the courier package. I'm absolutely convinced that those who just found their way into Debian have valuable perspectives--and that we stand to learn the most from listening to them.

We should also take seriously what Russ Allbery noted in the discussion: "This says bad things about the project's sustainability and I think everyone knows that." Volunteers move on--that’s normal and expected. But it makes it all the more important that we put effort into keeping Debian's contributor base at least stable, if not growing.

Project-wide LLM budget for helping people

Lucas Nussbaum has volunteered to handle the paperwork and submit a request on Debian’s behalf to LLM providers, aiming to secure project-wide access for Debian Developers. If successful, every DD will be free to use this access--or not--according to their own preferences.

Kind regards Andreas.

We are pleased to announce that AMD has committed to sponsor DebConf25 as a Platinum Sponsor.

DebConf25 is accepting sponsors! Interested companies and organizations may contact the DebConf team through sponsors@debconf.org, and visit the DebConf25 website at https://debconf25.debconf.org/sponsors /become-a-sponsor/.

We are very excited to announce that Debian has selected nine contributors to work under mentorship on a variety of projects with us during the Google Summer of Code.

Here is a list of the projects and students, along with details of the tasks to be performed.

Project: Quality assurance and continuous integration for biological and medical applications inside Debian

• Intern: Harish Chavre

Deliverables of the project: Continuous integration tests for Debian Med applications lacking a test, Quality Assurance review and bug fixing if issues might be uncovered.

Project: Device-specific Tweaks Management

• Intern: Mohammed ElDegwi

Deliverables of the project: Analysis and discussion of the current state of device tweaks management in Debian and Mobian. Proposal for a unified, run-time approach. Packaging of this service and tweaks data/configuration for at least one device.

Project: Enhancing Debian packages with ROCm GPU acceleration

• Interns: Spaarsh, utk4r-sh

Deliverables of the project: New Debian packages with GPU support. Enhanced GPU support within existing Debian packages. More autopackagetests running on the Debian ROCm CI.

Project: Make Debian for Raspberry Pi Build Again

• Interns: Kurva Prashanth

Deliverables of the project: Refreshing the set of daily-built images. Having the set of daily-built images become automatic again—that is, go back to the promise of having it daily-built. Write an Ansible playbook/Chef recipe/Puppet whatsitsname to define a virtual serve and have it build daily. Do the (very basic!) hardware testing on several Raspberry computers. Do note, naturally, this will require having access to the relevant hardware.

Project: Package LLM Inference Libraries

• Intern: k1000dai

Deliverables of the project: Eventually I hope we can make vLLM into Debian archive, based on which we can deliver something for LLM inference out-of-the-box. If the amount of work eventually turns to be beyond my expectation, I'm still happy to see how far we can go towards this goal. If the amount of work required for vLLM is less than I expected, we can also look at something else like SGLang, another open source LLM inference library.

Project: Autopkgtests for the rsync package

• Intern: puer robustus

Deliverables of the project: Autopkgtests for the rsync package.

Project: Enhancing Salsa CI in Debian

• Interns: Aayush (@44yu5h), aquilamacedo

Deliverables of the project: More features, robustness, speed.

Congratulations and welcome to all the contributors!
