Why Ubuntu 25.10 Snapshot 2 Is a Must-Try for Linux Testers
If you’re a Linux enthusiast, developer, or tester, you’ve probably heard the buzz about Ubuntu 25.10 Snapshot 2, codenamed Questing Quokka. Released on June 26, 2025, this second monthly snapshot in the Ubuntu 25.10 development cycle is generating excitement in the Linux community. But what makes this snapshot so special? Why should you, as a Linux tester, dive in and give it a spin? In this comprehensive blog post, we’ll explore the reasons why Ubuntu 25.10 Snapshot 2 is a must-try for Linux testers, diving into its new features, automation advancements, hardware support, and how it empowers testers to shape the future of Ubuntu. Let’s unpack why this snapshot deserves your attention!
A New Era of Ubuntu Development
For two decades, Ubuntu has stuck to its predictable six-month release cycle, with Long Term Support (LTS) releases every two years. This cadence has served the community well, but as software engineering evolves, so must Ubuntu. The introduction of monthly snapshots, starting with Ubuntu 25.10, marks a significant shift in how Canonical approaches development. These snapshots, like Snapshot 2, are curated milestones from the development stream, designed to enhance testing, improve automation, and catch issues early. They’re not production-ready, but they’re perfect for testers who want to get their hands dirty with the latest Ubuntu innovations.
Why Ubuntu 25.10 Snapshot 2 is a must-try for Linux testers lies in its role as a testing ground for Canonical’s new automated workflows. These snapshots aim to move away from “deep institutional knowledge” toward transparent, repeatable, and testable processes. For testers, this means a chance to influence Ubuntu’s development pipeline while exploring cutting-edge features.
What’s New in Ubuntu 25.10 Snapshot 2?
Ubuntu 25.10, set for its stable release on October 9, 2025, is shaping up to be a feature-packed interim release. Snapshot 2 builds on the foundation laid by Snapshot 1 (released May 29, 2025) and incorporates the latest development changes. Here’s a closer look at what testers can expect:
1. GNOME 49 Desktop Environment
One of the standout features of Snapshot 2 is the inclusion of GNOME 49, the latest iteration of the popular desktop environment. GNOME 49 brings a refined user experience with improved performance, smoother animations, and enhanced accessibility features. For testers, this is a golden opportunity to evaluate how GNOME 49 performs on various hardware configurations and report any regressions or bugs. Since Ubuntu 25.10 has dropped support for GNOME on X.Org, Snapshot 2 is Wayland-only, making it a critical testing ground for Wayland compatibility.
2. GCC 15 System Compiler
Snapshot 2 ships with GCC 15, the latest system compiler, which promises better optimization and support for modern programming standards. For developers and testers, this means you can compile and test applications with the newest compiler features, ensuring compatibility and performance improvements. If you’re working on software development, testing GCC 15 in a real-world environment like Snapshot 2 is invaluable.
3. Updated Linux Kernel (6.16 or 6.17)
While the exact kernel version for Ubuntu 25.10 is still under consideration (likely Linux 6.16 or 6.17), Snapshot 2 includes the latest kernel updates available at the time of its release. This brings improved hardware support, especially for newer devices, and enhanced performance. Testers can evaluate how the kernel handles their hardware, particularly on platforms like AMD64, ARM64, and RISC-V, which are seeing significant optimizations in this cycle.
4. New Default Applications
Ubuntu 25.10 Snapshot 2 introduces two new default applications: Loupe (an image viewer) and Ptyxis (a terminal emulator). These replacements for older defaults offer modern interfaces and improved functionality. Testers can assess their stability, usability, and integration with the GNOME desktop, providing feedback to ensure they meet user expectations before the stable release.
5. Enhanced RISC-V Support
RISC-V is gaining traction as an open-source architecture, and Ubuntu 25.10 is doubling down on its support. Snapshot 2 includes updated RISC-V hardware requirements and optimized server images, making it a prime opportunity for testers with RISC-V hardware (like the SiFive HiFive Unmatched) to put this support to the test.
6. TPM-Backed Full Disk Encryption
Security is a priority in Ubuntu 25.10, and Snapshot 2 includes advancements in TPM-backed full disk encryption with improved recovery key management. Testers can evaluate how well this feature works across different hardware setups, ensuring robust security for the final release.
7. Dropping Xorg for Wayland
A major shift in Ubuntu 25.10 is the complete removal of the Xorg session in favor of Wayland. Snapshot 2 is a critical milestone for testers to verify Wayland’s compatibility with applications, drivers, and workflows. If you rely on specific software or hardware, testing in Snapshot 2 can help identify any Wayland-related issues early.
Why Testers Should Care About Monthly Snapshots
You might be wondering, “Why not just stick to daily builds or wait for the beta?” The answer lies in the purpose of these monthly snapshots. Unlike daily builds, which can be unstable and harder to track, snapshots are curated milestones that provide a more cohesive testing experience. They’re not as polished as beta releases but offer a balance between bleeding-edge features and a structured testing environment. Here’s why Ubuntu 25.10 Snapshot 2 is a must-try for Linux testers:
1. Early Bug Detection
Snapshots are designed to catch major issues earlier in the development cycle. By testing Snapshot 2, you’re helping Canonical identify regressions and blockers before they become critical in the beta or stable phases. Your feedback can directly impact the quality of the final Ubuntu 25.10 release.
2. Testing Automation in Action
Canonical is leveraging tools like Temporal, an open-source durable execution solution, to automate its release pipeline. Snapshot 2 is a product of these new automated workflows, which aim to reduce human error and improve build reproducibility. Testers can evaluate whether these processes are producing reliable, working builds, providing insights that shape Ubuntu’s future release strategy.
3. Broad Hardware Support
Snapshot 2 supports a wide range of platforms, including:
- Desktop images: AMD64, ARM64
- Server images: AMD64, ARM64, PowerPC, RISC-V, IBM Z
- WSL images: For Windows Subsystem for Linux
- Pre-installed images: For Raspberry Pi and other devices
- Netboot tarball: For network installations
This diversity makes Snapshot 2 an excellent opportunity to test Ubuntu on various hardware, from modern PCs to single-board computers like the Raspberry Pi.
4. Community Impact
By testing Snapshot 2, you’re contributing to the Ubuntu community. Your bug reports, feedback, and suggestions help refine the OS, benefiting millions of users worldwide. Canonical encourages testers to share their findings on forums like the Ubuntu Community Hub or mailing lists, making your voice a vital part of the development process.
