Lyrical Luth Test and Tutorial Party Instructions
10,000 tickets, C++20 transition, and swag for top contributors—join the test drive.
The Robot Operating System (ROS) 2 team has launched a community-wide testing and tutorial party for its next distribution, Lyrical Luth, scheduled for release on May 22, 2026. The initiative aims to validate the distro across a wide matrix of system setups before the final cut. Each test ticket specifies a combination of host OS (Ubuntu Resolute 26.04, Windows 11, or RHEL-10), CPU architecture (AMD64 or ARM64), RMW/DDS vendor (FastDDS, CycloneDDS, ConnextDDS, or Zenoh), and build type (binary, Debian, or source). The project is particularly keen to get testers on Windows and RHEL, where internal resources are thinner.
Participants are asked to claim tickets from the GitHub project board, install the Lyrical Luth beta using their chosen method, and then run through a set of official ROS tutorials. If a tutorial works as expected, the ticket is closed as completed; otherwise, errors are documented for fixes. With 10,000 tickets to process and the shift to C++20 in Lyrical, the team anticipates needing to update tutorials and fix broken source builds. As a thank-you, the top 20 contributors can choose between ROS Lyrical swag or an OSRA membership. Registration via a Google Form is required for swag eligibility, and the party closes on May 14, 2026.
- ROS 2 Lyrical Luth will be released May 22, 2026, and requires community testing across 10,000 tickets.
- Test setups combine OS (Ubuntu 26.04, Windows 11, RHEL-10), architecture (AMD64/ARM64), RMW vendor, and build type.
- Top 20 contributors receive either ROS Lyrical swag or OSRA membership; testing runs until May 14, 2026.
Why It Matters
Community testing ensures ROS 2 Lyrical Luth runs reliably on diverse platforms, critical for robotics developers relying on the stack.
