Ubuntu 22.04 LTS is Equipped with Linux Kernel 5.19 — From Ubuntu 22.10 Kinetic Kudu!

With the launch of Ubuntu 22.04.2 LTS quickly approaching, Canonical has upgraded its long-term supported Jammy Jellyfish series to the Linux 5.19 kernel from Kinetic Kudu in Ubuntu 22.10 for an even more efficient and secure user experience!

Initially slated for early February 2023, the Ubuntu 22.04.2 LTS point release will come with Linux 5.19 HWE (Hardware Enablement) from the Ubuntu 22.10 update–this is an unprecedented development as it’s the first time a newer kernel will be featured in this type of Jammy Jellyfish point release! By introducing this all-new technology to its users, those who require it can now take advantage of enhanced hardware support and stability when using their systems running on Ubuntu 22.04 LTS

If you are running Ubuntu 22.04 LTS, the latest kernel might not be necessary since it already has Linux 5.15 LTS, which will deliver security updates for over three and a half years – from now until October 2026!

Linux kernel 5.19 is here, packing new features that allow for ZSTD-compressions of firmware files and support for AMD’s Secure Nested Paging feature. To top it off, you’ll find updates to Loongson’s “LoongArch” RISC ISA CPU architecture as well as Intel’s revolutionary “in-field scan” mechanism designed to detect any problems in Intel CPUs.

Linux Kernel 5.19 offers features, such as “logged attribute replay” for simultaneous modification to multiple extended file attributes in an atomic fashion on the XFS filesystem, improved lockdown mode security, and performance boost for running numerous containers with EROFS read-only file system.

Now, if you want to take advantage of the new features found in Linux 5.19 HWE kernel, just copy and paste this command into your Ubuntu 22.04 LTS terminal:

sudo apt update && sudo apt full-upgrade

To ensure a secure and reliable experience, I suggest that you keep the long-term supported Linux 5.15 kernel until its end of life if it meets your requirements. Additionally, Canonical’s fresh real-time kernel will only function on Linux 5.15 LTS right now.

Get ready for the newest version of Ubuntu – 22.04.2 LTS, set to arrive on February 23rd, 2023! This upgrade brings with it an included Linux kernel 5.19 and upgraded packages from the previous iteration so that you won’t need to manually download hundreds of updates after installation is completed!

  1. The kernel 5.19 quickly became a problem for me.
    I use an old Dell Precision M4800 with a docking station.
    Both USB devices and monitors mounted on dock became unavailable.
    Reverting to 5.15 for now.
