Canonical released Ubuntu 22.10 “Kinetic Kudu” today, and while interim releases don’t get the same fanfare as LTS versions, they serve an important purpose in the Ubuntu ecosystem. They’re the proving ground for what lands in the next long-term support release, and for developers, they offer early access to updated toolchains that can matter for day-to-day work.
The Toolchain Updates That Actually Matter#
The headline developer-facing changes are in the default toolchain. Ubuntu 22.10 ships with GCC 12.2, Python 3.10.7, and OpenSSL 3.0 as the default. For those of us building and deploying applications, these aren’t just version bumps — they have real implications.
GCC 12 brings improved diagnostics and better C++20/23 support. If you’re working on C or C++ projects, the improved error messages alone are worth the upgrade. I’ve been using GCC 12 in containers for a few months now, and the quality-of-life improvements in compilation errors have saved me more debugging time than I’d like to admit.
Python 3.10 as the system default is noteworthy because it means the match statement (structural pattern matching) and improved error messages are now available out of the box. If you’ve been developing against 3.10+ features but your CI servers were still on 3.9, this simplifies things.
The OpenSSL 3.0 default is the one that will cause the most headaches. OpenSSL 3.0 deprecated a number of legacy algorithms and changed the provider architecture significantly. Applications that relied on older ciphers or the legacy API will need updates. I’ve already seen this cause issues in several Node.js projects where native modules were compiled against OpenSSL 1.1.
GNOME 43 and the Desktop Story#
For desktop users, Ubuntu 22.10 brings GNOME 43 with its new quick settings panel and continued GTK4/libadwaita migration. The quick settings redesign is genuinely useful — it consolidates Wi-Fi, Bluetooth, dark mode, and power settings into a single, cleanly organized panel.
The more interesting desktop change is the continued adoption of PipeWire as the default audio server, replacing PulseAudio. PipeWire has been remarkably stable in my experience, handling both audio and screen sharing (particularly in Wayland sessions) better than the PulseAudio/PulseVideo combination it replaces.
If you’re a developer who does screen sharing during pair programming sessions or demos, PipeWire on Wayland is a significant improvement. The days of “let me switch to X11 so screen sharing works” are finally numbered.
Snap Packages: The Ongoing Debate#
Ubuntu 22.10 continues Canonical’s push toward Snap packages, with Firefox remaining a Snap and more system applications moving to the format. This remains one of the most divisive decisions in the Ubuntu community.
I understand the arguments on both sides. Snaps solve real problems around dependency isolation and automatic updates. But the startup time penalty is noticeable, especially on older hardware, and the mandatory Snap Store backend frustrates those who prefer fully open infrastructure.
For server-side development — which is where most of us interact with Ubuntu professionally — Snaps are largely irrelevant. Server deployments use debs, containers, or direct binary deployments. The Snap debate is primarily a desktop concern, but it does affect developer workstations, and slow application startup times on your dev machine are a real productivity issue.
What This Means for the Next LTS#
The real value of Ubuntu 22.10 is as a preview of Ubuntu 24.04 LTS, which is about 18 months away. The toolchain choices being tested now — GCC 12, Python 3.10+, OpenSSL 3.0, PipeWire — will likely form the foundation of that release.
If you’re running Ubuntu 22.04 LTS in production (as many of us are), now is the time to start testing your applications against these newer toolchain versions. OpenSSL 3.0 migration in particular can be disruptive, and you don’t want to discover compatibility issues when you’re under pressure to upgrade.
I’ve started running our CI pipelines against both 22.04 and 22.10 base images to catch any toolchain compatibility issues early. It’s a small investment that pays off significantly when the next LTS drops.
My Take#
Interim Ubuntu releases don’t get a lot of love, and honestly, I wouldn’t recommend most people run them in production. The nine-month support window is too short for any serious deployment. But as a developer, installing 22.10 on a secondary machine or using it as a container base for testing is a smart move.
The most impactful change in this release is the OpenSSL 3.0 default. If you haven’t started testing your applications against OpenSSL 3.0, let this be your reminder. The migration from 1.1 to 3.0 is one of those changes that seems minor until it breaks your TLS configuration in production.
Ubuntu continues to be the dominant Linux distribution for cloud workloads and developer machines, and releases like 22.10 are part of why. They provide a structured, predictable path for toolchain evolution that the broader ecosystem can plan around. Not exciting, perhaps, but reliable — and in infrastructure, reliable wins.
