Canonical Upgrades Ubuntu 22.04 LTS to Linux Kernel 5.19

Ubuntu 22.04 LTS, also known as Jammy Jellyfish, has received a major upgrade to its Linux kernel. Canonical, the company behind Ubuntu, announced that the operating system's Linux kernel 5.15 will be upgraded to Linux 5.19. This will bring many new features and improvements to the popular open-source operating system.

Upgrading to Linux Kernel 5.19

Ubuntu 22.04 LTS users can upgrade to the Linux 5.19 HWE kernel by entering the command "sudo apt update && sudo apt full-upgrade" in the terminal application. The updated installer media will also include all update packages released since Ubuntu 22.04.1 LTS, which means users will not have to download hundreds of updates after installation.

New Features in Linux Kernel 5.19

The Linux Kernel 5.19 introduces several new features that will benefit Ubuntu users. The kernel now supports ZSTD compressed firmware files, which will result in faster boot times. Additionally, it supports AMD's secure nested paging function, Loongson's "LoongArch" RISC ISA CPU architecture, and Intel's new "in-field scan" mechanism to detect some issues in Intel CPUs.

Ubuntu 22.04.2 LTS

Canonical has announced that it will release Ubuntu 22.04.2 LTS on February 23, 2023. This version of Ubuntu will be based on Linux Kernel 5.19 by default, which means users who upgrade to the new kernel now will be ahead of the game.

Long-Term Support

Ubuntu 22.04 LTS will be supported until October 2026, which means users who upgrade to the Linux 5.19 kernel will have a stable and secure operating system for years to come. The LTS designation means that Canonical will provide updates and security patches for the duration of the support period.
