Ubuntu 22.04 LTS “Jammy Jellyfish” Released


Canonical has just released Ubuntu 22.04 LTS “Jammy Jellyfish” on schedule. The new version of the Linux operating system provides confidential cloud computing, a new real-time kernel for industrial applications, Arm optimization, support for Raspberry Pi SBCs, as well as enterprise support Active Directory, PCI-DSSHIPAA, FIPS and FedRAMP conformity.

Confidential computing aims to improve data protection and privacy in public clouds without requiring changes to existing application deployments, and Ubuntu 22.04 supports Azure Privacy Virtual Machines. Speaking of cloud computing, Canonical also says it has optimized Ubuntu 22.04 LTS images for AWS Graviton for better performance on Arm servers. New real-time PREEMPT_RT kernel is currently in beta and available for x86 and Aarch64 architectures. It is designed for telecommunications (5G gateways) as well as other latency-sensitive applications such as industrial automation and robotics.

Ubuntu 22.04 LTS is also the first long-term support release with Ubuntu desktop for Raspberry Pi 4, including models with only 2 GB of RAM thanks to zswap. Boards with less memory such as the Raspberry Pi Zero 2W are also supported with an Ubuntu 22.04 server image. Developers relying on Ubuntu WSL in Windows 10/11 can also immediately upgrade to the latest OS version. Select Dell workstations even come with Ubuntu WSL pre-installed to help develop AI/ML/DL workflows. Ubuntu multi pass also got Apple M1 support, so you can run Ubuntu 22.04 LTS virtual machines on Apple Arm hardware.

Ubuntu 22.04 LTS comes with the latest GNOME 42 desktop environment supposed to dramatically improve usability, battery life through power profiles, and performance with desktop rendering up to twice as fast on Intel graphics drivers and Raspberry Pi. Canonical has also added support for default load of Rust for secure system-level programming, as well as OpenSSL v3 for enhanced security, and Linux 5.15 LTS was selected.

If you want to install or try Ubuntu 22.04 Desktop or Server, go to the download page. But it’s only for 64-bit x86 (AMD64) targets, and if you want to run it on Raspberry Pi hardware, there’s a dedicated page for specific images. I couldn’t find the beta Linux realtime kernel, but Canonical talks about their existing low latency kernel and PREEMPT_RT in a blog postand it should be based on linux rt 5.15. The operating system will be supported for 5 years until 2027 like all other LTS releases.

More details can be found in the announcement.
