Ubuntu 22.10 (Kinetic Kudu) delivers a refresh of core components and developer tools, focusing on newer kernels, desktops, and language runtimes.
| Category | Key Updates |
|---|---|
| Kernel | Linux 5.19 |
| Desktop | GNOME 43, Quick Settings |
| Toolchain | GCC 12.2, glibc 2.36 |
| Python | Python 3.10.7 |
| Cloud & Containers | OpenStack Zed, Kubernetes 1.25, containerd 1.6.8 |
| Security | OpenSSL 3.0.7, Polkit priv escalation fix |
| Deprecated | Python 2 removed |
What's new with the Linux kernel in 22.10?
Ubuntu 22.10 ships with the Linux 5.19 kernel. This brings support for newer hardware, including Intel's Ivy Bridge and Haswell graphics improvements, and initial support for Apple M1 Pro/Max/Ultra systems.
In practice, this means better out-of-the-box compatibility for the latest laptops and development boards. The kernel update also includes the usual slew of performance optimizations and driver updates that are critical for developers working on cutting-edge hardware.
How is the GNOME 43 desktop experience different?
The most visible change is the new Quick Settings menu. You can now access key settings like Wi-Fi, Bluetooth, and dark mode from the top-right system menu without opening the full Settings application.
GNOME 43 also introduces a revamped file chooser dialog, which is something developers interact with constantly. It's more intuitive and should save a few clicks when you're opening or saving projects.
What toolchain and language updates should developers expect?
The core toolchain has been bumped to GCC 12.2, GNU C Library (glibc) 2.36, and LLVM 15. This matters for C/C++ and Rust developers who need the latest compiler optimizations and language support.
Python 3.10.7 is the default, and notably, Python 2 has been completely removed from the main archive. If you're maintaining legacy Python 2 code, you'll need to plan your migration or use a container. Ruby 3.0, PHP 8.1, and Go 1.19 are also included for full-stack development.
Are there updates for cloud and container deployments?
Yes, the cloud stack gets a significant refresh. Kubernetes 1.25 is available, alongside containerd 1.6.8 and runc 1.1.4. For OpenStack deployments, the 'Zed' release is included, which is essential for building and managing private clouds.
MicroK8s and LXD also have their latest releases snap-packed. This keeps the container and orchestration tooling current for DevOps workflows without interfering with the core system packages.
What are the critical security updates?
The most important security change is the update to OpenSSL 3.0.7. This is a major version jump that developers need to be aware of for their applications that handle cryptography.
A critical privilege escalation vulnerability in Polkit (CVE-2021-4034) has been patched. This was a significant issue in previous releases, so this fix is a key reason to upgrade for any multi-user system.
FAQ
Is Python 2 still available in Ubuntu 22.10?
No, Python 2 has been completely removed from the main archive. Legacy applications relying on it will need to use a container, snap, or a third-party repository like Dead Snakes.
Can I upgrade directly from Ubuntu 20.04 LTS to 22.10?
Technically yes, but it's not the recommended path. LTS-to-LTS upgrades (e.g., 20.04 to 22.04) are better supported. Going to an interim release like 22.10 is possible but may require more manual intervention.
Does the new kernel support the latest Intel Alder Lake processors?
Yes, the Linux 5.19 kernel includes improved support and scheduling for Intel's 12th Gen Alder Lake hybrid architecture, which should lead to better performance on these newer CPUs.
What happened to the Ubuntu Desktop installer slideshow?
It was replaced with a new, minimal installer that uses a responsive design. It's faster and provides a more modern first-boot experience.
Is Wayland still the default for NVIDIA users?
No. Due to driver and experience issues, the default session for systems using the proprietary NVIDIA driver has been switched back to Xorg. Wayland remains the default for other graphics drivers.
