Canonical says it plans to release an Ubuntu 22.04.3 LTS maintenance release update on August 10th if all goes well, and will upgrade to the same Linux 6.2 kernel as Ubuntu 23.04 (Lunar Lobster).

Canonical has already rolled out the Linux 6.2 HWE kernel to existing Ubuntu 22.04.2 LTS users.

IT Note: If you are currently using this version, you can upgrade to the 6.2 kernel by running the commands sudo apt update && sudo apt full-upgrade in a terminal.

Linux 6.2 was released as a HWE (Hardware Enabled) kernel to provide a smoother installation experience, as well as better hardware support for those looking to deploy the Ubuntu 22.04 LTS (Jammy Jellyfish) operating system family on newer computers.

Ubuntu 18.04 LTS (Bionic Beaver) continues its tradition of providing commercial support for Ubuntu LTS releases in the form of Extended Security Maintenance (ESM), which reaches the end of standard support after five years of maintenance. The Ubuntu 16.04 ESM product will end support in April 2024.

Ubuntu 18.04 LTS was released five years ago, on April 26, 2018, and will now be supported by Canonical for five years through April 2028 with critical bug and security fixes through the Extended Security Maintenance (ESM) package of Ubuntu Advantage for Infrastructure.

Enterprises that rely on stability and are not yet able to upgrade to a newer version of Ubuntu LTS are encouraged to purchase an Ubuntu Pro subscription if they want to benefit from five years of support for their Bionic Beaver installation.

Ubuntu Pro is available for amd64, arm64, s390X and PowerPC architectures, for desktops, servers, IoT devices, public clouds on AWS (Amazon Web Services), Azure and Google Cloud, as well as IBM Cloud and Oracle Cloud platforms.

“By subscribing to Ubuntu Pro, you can ensure that your Ubuntu 18.04 LTS deployment is fully supported through 2028. This extended support period provides ongoing assistance and maintenance for your workloads,” Canonical said.

Those who do not plan to purchase an Ubuntu Pro subscription are urged to upgrade their installations to Ubuntu 22.04 LTS (Jammy Jellyfish) as soon as possible, which brings an updated kernel with support for more devices, as well as many updated packages.

Canonical notes that the upgrade path from Ubuntu 18.04 LTS support is through Ubuntu 20.04 LTS and then to Ubuntu 22.04 LTS.

Users who are still running Ubuntu 18.04 after May 31, 2023 will not receive any security updates, meaning this installation will be at risk.

The latest generation of Dell XPS 13 Plus Developer Edition laptops feature Intel Core i7 12th generation “Alder Lake” processors, up to 32GB of system memory and 2TB of NVMe storage, a choice of FHD+/3.5k OLED/4K displays, Intel Wi-Fi 6E support and other modern connectivity. Dell’s new order will now offer Ubuntu 22.04.1 LTS for those who choose the “Developer Edition”, sold alongside the standard Dell XPS with Microsoft Windows 11.
The Dell XPS 13 Plus is priced at $1,299 with an entry-level Core i5 1240P configuration and 8GB of RAM. Or an optional Core i7 1260P processor with 16GB of RAM is available, with pricing starting at $1,599. Interestingly, ordering the flagship Core i7 1280P model with Ubuntu 22.04 LTS pre-installed is not currently allowed in the US market.

Those developers wishing to learn more about Ubuntu 22.04 LTS pre-installed on the latest Dell XPS can visit the DELL.com website at

It’s worth pointing out that this Dell XPS Alder Lake model is one of the models that uses the newer Intel IPU6 webcam technology, which currently requires binary blobs to use non-lite code on Linux. So some community techs are advising against using these laptops because proper open source support can take a year or more.

Jammy has proposed a revision to systemd 249.11-0ubuntu3.4, and is currently setting “ManagedOOMSwap=auto” on the root slice (-.slice), and will push the update to stable releases soon.

Previously Ubuntu 22.04 LTS had been using “ManagedOOMSwap=kill” by default, resulting in the system always killing important application processes with high resource usage by mistake.

With the change, system-oomd’s default policy will be limited to monitoring memory pressure, rather than stretching its hands to blindly manage swap usage.

With the new policy of not terminating large swap usage or proposing to increase swap size, users will no longer see applications being terminated unexpectedly, and the Ubuntu Linux development team is exploring other suggestions and ideas.
