Lubuntu is a variant of Ubuntu that uses the LXQt desktop environment. (Versions prior to 18.10 shipped with the LXDE desktop.) It includes essential applications and services for daily use, including office suite, PDF reader, image editor and multimedia players. A distribution available for both 32-bit and 64-bit computers, Lubuntu is intended to be user-friendly, lightweight and energy efficient.

Kubuntu is a free, user-friendly Linux distribution based on KDE's desktop software and on the Ubuntu operating system. It has a biannual release cycle. Besides providing an up-to-date version of the KDE desktop at the time of the release, the project also releases updated KDE packages throughout the lifetime of each release.

Edubuntu is a partner project of Ubuntu, a distribution suitable for classroom use. The aim is that an educator with limited technical knowledge and skill will be able to set up a computer lab, or establish an on-line learning environment, in an hour or less, and then administer that environment without having to become a fully-fledged Linux geek.

MeshCore is a relatively new project, started in January 2025, that aims to build a scalable mesh network using low-power long-distance radios. While many other projects of the same general nature have been tried before, MeshCore grew quickly because of its more efficient message routing and enthusiastic community. In early 2026, an early proponent of the project made a sudden shift that left the rest of the community stunned and embroiled in a trademark dispute.

Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux. It is available for the x86_64 and AArch64 processor architectures.

Many organizations require US Federal Information Processing Standard (FIPS) certification of the crypto code they are running. The certification process is lengthy, but the bigger problem is that the way the crypto subsystem is built into the kernel makes the result unable to be reused across kernel updates. I have proposed a patch series that decouples the crypto subsystem into a standalone loadable module, allowing a certified crypto module to be reused with multiple kernels and, thus, requiring fewer lengthy recertification delays.

Andrew Nesbitt has written a blog post detailing a recent incident with the jqwik library for property-based testing in Java. On May 25, the 1.10.0 release of jqwik included a change that attempts to instruct coding agents to disregard previous instructions and delete jqwik tests and code.

I think this is a new class of supply-chain input worth keeping an eye on, mostly because of how little of the existing tooling has any opinion about it. A System.out.print of sixty-eight bytes of plain ASCII isn't the kind of thing scanners are looking for, since those watch for install hooks, network calls, filesystem writes, obfuscated strings and the like. The jar makes the same syscalls it made in 1.9, and because the change was committed and released by the legitimate maintainer through the normal build, it's clean from a SLSA point of view too: the provenance is what it should be. Anyone who reads the diff can see what it does, but a patch bump of a test-scoped dependency is not where most projects spend their review time.

Coyote Linux is a security-centric distribution of Linux designed to provide firewall, VPN, IP routing and related services. It is built on Alpine Linux with an immutable firmware architecture and safe rollback capability. The product's other interesting features include separation of configuration files from the system image, minimal attack surface through reduced footprint, appliance-style deployment and upgrades, and Ed25519 firmware signature verification. The Coyote Linux project has been providing firewall and router solutions since 2000 when its early firewall releases were designed to fit on a single floppy disk.

Senpai Respins is a set of (principally) MX Linux respins with Cinnamon, GNOME, LXDE, LXQT, MATE and Moksha desktops and window managers, user interfaces that the upstream project does not offer. It also provides a respin of Linux Mint Debian Edition (LMDE) with MATE, and MX Linux with the Parrot distribution installed on top of it. The MX Linux variants offer a choice between the systemd and SysV init systems. Other than integrating a new desktop into an existing distribution, Senpai brings very few other modifications, leaving the software composition and visual appearance of the upstream project intact.

Version 1.96.0 of the Rust programming language has been released. Changes include a new set of Copy-implementing Range types, assertions with pattern matching, a number of stabilized APIs, and two Cargo vulnerability fixes.

RuscaLinux is a desktop Linux distribution based on Debian's "Stable" branch and featuring the GNOME desktop. The project's goal is to provide a complete, ready-to-go desktop with a curated software set, but without any update mechanisms. This is the distribution's deliberate design choice; it provides no live repositories so the system stays exactly as installed and tested, and any new versions arrive as fresh ISO images. It is a stability-first model, similar in spirit to immutable distributions but reached through a different path.

Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux. It is available for the x86_64 and AArch64 processor architectures.

PCLinuxOS is a user-friendly Linux distribution with out-of-the-box support for many popular graphics and sound cards, as well as other peripheral devices. The bootable live DVD provides an easy-to-use graphical installer and the distribution sports a wide range of popular applications for the typical desktop user, including browser plugins and full multimedia playback. The intuitive system configuration tools include Synaptic for package management, Addlocale to add support to many languages and Mylivecd to create a customised live CD.

Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes. These qubes are implemented as virtual machines (VMs). This allows each component of the operating system to be isolated from other pieces, preventing compromises from spreading or information from leaking.

Gentoo developer Michał Górny has written a lengthy article explaining the philosophy and purpose of the Gentoo Linux distribution, in response to a thread on Mastodon:

Gentoo is a source-first distribution, which means the primary method of installing software is to build it from source. Of course, that doesn't mean manually building stuff, following some kind of how-to: finding all the dependencies, installing them manually, going through a series of magical incantations, and eventually ending up no better than if we were installing a binary package. The package manager takes care of all the necessary steps and more, making package installs easy; well, at least unless something fails. But I'm digressing...

[...] We try to build a friendly and welcoming community around Gentoo, and we truly want using Gentoo be an enjoyable experience. We want it to be a system that doesn't betray you.

Gnoppix Linux is a Debian-based distribution which can be run from a USB thumb drive or from a local drive. It is pre-loaded with essential Artificial Intelligence (AI) frameworks, libraries and development tools. It uses several popular desktop environments, including GNOME, KDE Plasma and Xfce. The project is an attempt to revive a Knoppix-based live distribution with the GNOME desktop that was first launched back in 2002.

In a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Amir Goldstein wanted to discuss his proposed documentation on adding new filesystems to the kernel. There are a number of unmaintained and untestable filesystems already in the kernel, which are a burden to VFS-layer developers who are trying to make sweeping changes, such as switching to folios and the "new" mount API. Goldstein's document is an attempt to head off the addition of filesystems that may increase that burden down the road.
