Ubuntu 22.04 LTS "Jammy Jellyfish" Launched by Canonical.

 Ubuntu 22.04 LTS "Jammy Jellyfish" was just published on time by Canonical. Cloud confidential computing, a new real-time kernel for industrial applications, Arm optimization, support for Raspberry Pi SBCs, enterprise Active Directory, PCI-DSS, HIPAA, FIPS, and FedRAMP compliance are all included in the next edition of the Linux operating system.

Confidential Computing promises to improve data security and privacy in public clouds without requiring any changes to existing application deployments, and Ubuntu 22.04 is compatible with Azure Confidential VMs. Canonical also claims to have improved Ubuntu 22.04 LTS images for AWS Graviton for better performance on Arm servers when it comes to cloud computing. PREEMPT RT, a new real-time kernel, is presently in beta and is available for both x86 and Aarch64 architectures. It's made for telco (5G gateways) and latency-sensitive applications like industrial automation and robotics.

Thanks to zswap, Ubuntu 22.04 LTS is also the first long-term support version featuring Ubuntu Desktop for Raspberry Pi 4 models with as little as 2GB RAM. With an Ubuntu 22.04 Server image, boards with less memory, such as the Raspberry Pi Zero 2 W, are also supported. Developers who use Ubuntu WSL on Windows 10/11 can also upgrade to the most recent version of the operating system right away. Some Dell workstations come pre-installed with Ubuntu WSL to make developing AI/ML/DL processes easier. Apple M1 compatibility has also been added to Ubuntu Multipass, allowing you to run Ubuntu 22.04 LTS virtual computers on Apple Arm hardware.

The latest GNOME 42 desktop environment is included in Ubuntu 22.04 LTS, which is said to improve usability, battery life through power profiles, and performance, with the desktop rendering up to twice as fast on Intel and Raspberry Pi graphics drivers. Canonical also selected Linux 5.15 LTS and provided default support for Rust for memory-safe systems-level programming, as well as OpenSSL v3 for better security.

Go to the download page if you want to install or trial Ubuntu 22.04 Desktop or Server. But that's only for 64-bit x86 (AMD64) targets; if you want to run it on Raspberry Pi hardware, you'll need to go to a separate website with particular images. I couldn't find the beta Linux real-time kernel, although Canonical mentions PREEMPT RT and their existing low-latency kernel in a blog post, and it should be based on Linux-rt 5.15. As with all prior LTS releases, the OS will be supported for five years, until 2027.
