Ubuntu at DevConf.CZ 2026
DevConf conference brought the free and open source community back to Brno on 18–19 June 2026, gathering developers, administrators, students, and contributors for two packed days of talks, demos, and hallway discussions. Ubuntu joined the event with a community booth and, as always, plenty of orange energy.
Showing up in another project’s home ground
DevConf has strong roots in the Fedora, CentOS Stream, CoreOS, and Red Hat communities, but its scope is much wider. The conference brings together people working on Linux, open infrastructure, immutable systems, developer tooling, security, and the many practical details that make open source usable in the real world.
For us, being there was about listening, comparing notes, answering questions, and meeting people who care about the same ecosystem.
Talks
The talks gave the event its real shape. The opening keynote, “How I learned to stop worrying and love CVEs – Hummingbird” set the tone with a practical look at the scale of modern vulnerability management and the limits of traditional manual patching workflows.
The sessions ranged from low-level Linux topics like “New security features in systemd” to cloud-native and developer-workflow topics such as “Network observability with eBPF and OpenTelemetry”.
The one that stuck with me most was “Who Dropped the Packet? Solving K8s Network Mysteries in Real-Time”, explaining how difficult Kubernetes networking problems, such as packets disappearing between services, nodes, and policies, can be addressed by tracing packet flow in real time with eBPF-based observability.
For those curious to learn more, all the talks are available on the DevConf.CZ 2026 YouTube playlist.
From talks to booth conversations
One of the best parts of DevConf was how naturally the talks carried into conversations at the booth. We were joining discussions already happening across the conference about security, reliability, observability, and the everyday work of maintaining open source systems.
Some visitors came with specific questions, about how we handle packaging, snaps, security updates, and what is coming next. Some were surprised to hear that Canonical is the company behind Ubuntu, and that it offers an entire ecosystem of open source solutions. Others stopped by because Ubuntu was their first Linux distribution, their current daily driver, or the system powering their infrastructure.
And, unsurprisingly, stickers helped spark good conversations.
Beyond the schedule
Not everything fitted neatly into the program. Some conversations happened at the booth, some continued at the evening party, and some were helped along by very good ice cream.
The most valuable takeaway was the connections made there, the ones that stay open long after the conference ends with an occasional keepalive.
Thank you, Brno
Thank you to the DevConf.CZ organizers, volunteers, speakers, attendees, and everyone who stopped by the Ubuntu booth.
Special thanks to our community member Michal Kohútek for helping at the booth and keeping Canonical’s presence welcoming and lively.
