Ubuntu Cinnamon is an official flavour of the Ubuntu distribution featuring the Cinnamon desktop. The project strives to offer modern tools while providing a user-friendly desktop which will feel familiar for users coming from other operating systems, such as Microsoft Windows.
Ubuntu Budgie (previously budgie-remix) is an Ubuntu-based distribution featuring the Budgie desktop, originally developed by the Solus project. Written from scratch and integrating tightly with the GNOME stack, Budgie focuses on simplicity and elegance, while also offering useful features, such as the Raven notification and customisation centre.
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.
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit. "Ubuntu" is an ancient African word, meaning "humanity to others". The Ubuntu distribution brings the spirit of Ubuntu to the software world.
The
Power Management
and Scheduling in the Linux Kernel Summit, which still goes by the
historical acronym OSPM, was held in Cambridge, UK, in mid-April. As has
become traditional, the presenters at that event have since written
summaries of their sessions, and this work has kindly been made available
to LWN for publication. The third day's sessions covered a wide range of
topics, including GPU affinity, profile-guided scheduling,
paravirtualization scheduling, quality of service, and more.
Writeback is the process of ensuring that dirty pages or folios in the page
cache are flushed to the disk, so that changes to those files are made
persistent. In a filesystem-track session at the 2026
Linux Storage,
Filesystem, Memory Management, and BPF Summit, Jeff Layton wanted to
discuss whether the writeback operation should be initiated earlier than it
is today. The consensus seemed to be that it should be done earlier, but
the path toward making that happen was less clear.

list of Mastodon posts about the changes in the systemd v261 release.
The Mastodon format makes the reading harder, but there is a lot of useful
information there.
Version:next-20260626 (linux-next)
Released:2026-06-26
The
Git v2.55.0-rc2
testing release appeared on June 23, suggesting that the final Git
2.55 release can be expected in the near future. While this Git update
lacks radical new features, it does include a number of improvements that
regular Git users will appreciate, including commands to easily edit the
commit history, more formatting options, fsmonitor support for Linux, and
more.

The Linux Foundation, in
a
letter co-signed by a large range of organizations and companies, has
announced the launch of "Akrites", a project to fast-track vulnerability
fixes into projects.
As Akrites works upstream to fix projects at the source, we commit
to support downstream efforts to secure critical infrastructure
before it can be exploited. When patches are released to the
public, adversaries are able to utilize AI to rapidly reverse
engineer the underlying vulnerabilities, develop exploits, and
launch attacks. The success of our efforts therefore will be
measured in patch deployment, not publication. We will partner with
critical infrastructure owners and operators, civil society
efforts, and governments as they increase coordination to achieve
these goals.
Confidentiality is non-negotiable: An undisclosed flaw in a widely
deployed package is, in effect, a weapon, and the program is built
first to prevent leaks. Fixes flow back into each project's own
home, working with the maintainers. The engineering resources and
other capabilities provided by Akrites participants contribute to
this effort. Additionally, when a critical package has no one
maintaining it, Akrites will stand as the maintainer of last resort
so a fix can still reach everyone in a timely fashion. We will also
align with government efforts so that public and private defenders
move together, rather than in a disjointed fashion.
Manjaro Linux is a fast, user-friendly, desktop-oriented operating system based on Arch Linux. Key features include intuitive installation process, automatic hardware detection, stable rolling-release model, ability to install multiple kernels, special Bash scripts for managing graphics drivers and extensive desktop configurability. Manjaro Linux offers Xfce as the core desktop options, as well as KDE, GNOME and a minimalist Net edition for more advanced users. Community-supported desktop flavours are also available.
Uncom OS is Russian commercial Linux distribution based on Ubuntu's long-term support branch and localised into Russian. It is developed by Advilabs-Rus LLC. Some of the distribution's more interesting features include a custom application store, out-of-the-box support for Flatpak packages, a Windows-style dock panel, extended support for VPN protocols, a custom application for restoring system integrity, and use of Bottles to run Windows applications. Besides commercial "Home", "Business" and "Education" editions of Uncom OS, the company also offers a freely downloadable trial variant for testing purposes.
MinIO is
a popular object-storage server that offered compatibility with the Amazon Simple Storage Service (S3)
API. In December 2025, the company behind the project (also named MinIO)
announced
that the project was in maintenance mode and would not accept new changes; it
was archived
completely in February 2026. MinIO users have been hunting for alternatives
since then, but the array of choices can be baffling. While many other projects
aim to fill the space, their strengths and areas of focus tend to vary. Two of
the alternatives—Ceph and Garage—are particularly compelling,
and both offer solid S3 compatibility.
Version:next-20260625 (linux-next)
Released:2026-06-25
Version 6.0.0 of the Podman
container-management tool has been released. Notable new features
include the ability to set multiple static IP addresses for
containers, improvements in network isolation that make Podman more
compatible with Docker, changes to the way Quadlet
commands function, many new options for many existing podman
commands, and a
rewrite of Podman's configuration file handling. There are many
breaking changes; see the release
notes for a full list of all new features, changes, and bug fixes.
There is a lot of work going into eliminating exploitable bugs from the
kernel and preventing the addition of new ones. Even if this work is
maximally successful, though, there is no chance that the kernel will be
free of these bugs anytime soon. Thus, there is also ongoing interest in
hardening the kernel to make the existing bugs more difficult to exploit.
The upcoming 7.2 kernel release will include a change to how dynamically
allocated structures are placed in memory to make them harder to overwrite,
while a project to randomize structure layout at boot time has a rather
longer timeline.
