Ubuntu Kylin is an official Ubuntu flavour whose primary goal is to create a variant of Ubuntu optimised for Chinese users (using the Simplified Chinese writing system), although it also supports other languages. The default desktop is called UKUI (Universal Kylin User Interface) which is based on MATE desktop and is developed with the Qt toolkit. UKUI strives to adhere to the friendly-and-simple design concept. The distribution also includes more than 20 applications developed in-house, including Kylin Assistant, Kylin Video, Kylin Screenshots and Software Center.

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.

Version:next-20250918 (linux-next) Released:2025-09-18

Time-slice extension is a proposed scheduler feature that would allow a user-space process to request to not be preempted for a short period while it executes a critical section. It is an idea that has been circulating for years, but efforts to implement it became more serious in February of this year. The latest developer to make an attempt at time-slice extension is Thomas Gleixner, who has posted a new patch set with a reworked API. Chances are good that this implementation is close to what will actually be adopted by the kernel.

Version 1.90.0 of the Rust language has been released. Changes include switching to the LLD linker by default, the addition of support for workspace publishing to cargo, and the usual set of stabilized APIs.

Security updates have been issued by AlmaLinux (gnutls, mysql:8.4, opentelemetry-collector, and python-cryptography), Debian (nextcloud-desktop), Fedora (chromium, firefox, forgejo, gitleaks, kernel, kernel-headers, lemonldap-ng, perl-Cpanel-JSON-XS, and python-pip), Red Hat (firefox and libxml2), Slackware (expat and mozilla), SUSE (avahi, bluez, cups, curl, firefox-esr, gdk-pixbuf, gstreamer, java-1_8_0-ibm, krb5, net-tools, podman, raptor, sevctl, tkimg, ucode-intel, and vim), and Ubuntu (linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-hwe, linux-kvm, linux-oracle, linux-fips, linux-azure-fips, linux-gcp-fips, and linux-gcp-6.14, linux-oracle, linux-oracle-6.14).

The Universal Blue project has announced the release of Bluefin LTS, an image-based distribution similar to Bluefin that uses CentOS Stream 10 and EPEL instead of Fedora as its base:

Bluefin LTS ships with Linux 6.12.0, which is the kernel for the lifetime of release. An optional hwe branch with new kernels is available, offering the same modern kernel you'll find in Bluefin and Bluefin GTS. Both vanilla and HWE ISOs are available, and you can always choose to switch back and forth after installation. [...]

Bluefin LTS provides a backported GNOME desktop so that you are not left behind. This is an important thing for us. James has been diligently working on GNOME backports with the upstream CentOS community, and we feel bringing modern GNOME desktops to an LTS makes sense.

Version 7.0 of the Tails portable operating system has been released. This is the first version of Tails based on Linux 6.12.43, Debian 13 ("trixie") and GNOME 48. It uses ztsd instead of xz to compress the USB and ISO images to deliver a faster start time on most computers. The release is dedicated to the memory of Lunar, "a traveling companion for Tails, a Tor volunteer, Free Software hacker, and community organizer":

Lunar has always been by our side throughout Tails' history. From the first baby steps of the project that eventually became Tails, to the merge with Tor, he's provided sensible technical suggestions, out-of-the-box product design ideas, outreach support, and caring organizational advice.

Outside of Tor, Lunar worked on highly successful Free Software projects such as the Debian project, the Linux distribution on which Tails is based, and the Reproducible Builds project, which helps us verify the integrity of Tails releases.

See the changelog for a full list of fixes, upgraded applications, and removals. LWN covered Tails Project team leader intrigeri's DebConf25 talk in July.

A team of researchers from Frondeur Labs, DistributedApps.ai, and OWASP has developed a new machine learning framework designed to help defenders anticipate attacker behavior across the stages of the Cyber Kill Chain. The work explores how machine learning models can forecast adversary techniques and generate structured attack paths.
