Drauger OS 7.8 aims to turn Ubuntu into a gaming Linux distro with KDE Plasma

Drauger OS 7.8 (codename 'Urgal') is a new release of an Ubuntu-based Linux distribution focused on gaming. Key highlights include Linux kernel 7.0 with day-one NTSYNC support for improved gaming performance, KDE Plasma 6.5 on Wayland by default with better VRR and HDR support, and Firefox shipped as a Flatpak instead of a Snap package. The distro competes with established gaming-focused Linux distributions like Bazzite and CachyOS, taking a distinct approach by building on Ubuntu's foundation.

AnduinOS 1.4 End of Life (EOL) Announcement and Upgrade Guide

Người dùng nên nâng cấp lên AnduinOS 2.0 (dựa trên Ubuntu 26.04 LTS, hỗ trợ đến 4/2031) bằng lệnh do_anduinos_upgrade hoặc quay về AnduinOS 1.1. Bản 2.0 bổ sung Apkg package manager, Linux Kernel 7.0 và GNOME 50.

Lập trình viên nên đọc bài này để cập nhật về các phiên bản mới của AnduinOS, đặc biệt là việc chuyển sang Apkg thay cho hệ thống quản lý gói cũ, giúp tối ưu hóa hiệu suất và bảo mật cho dự án hoặc hệ thống của mình.

pedit COW kernel local privilege escalation vulnerability mitigations

A local privilege escalation vulnerability (CVE-2026-46331), dubbed 'pedit COW', has been disclosed in the Linux kernel's tc-pedit traffic control module with a CVSS score of 7.8 (HIGH). It affects Ubuntu releases from 18.04 LTS through 25.10, with Ubuntu 26.04 LTS receiving AppArmor mitigations. On non-container hosts, a published exploit allows local users to gain root. In container environments, it may also enable container escape. Until kernel patches are released, the mitigation involves blocking the act_pedit kernel module via modprobe configuration, regenerating initramfs, and unloading the module. Step-by-step instructions are provided for applying and later removing the mitigation.

Ubuntu 26.04 LTS has fixed its missing video/audio thumbnails

Ubuntu 26.04 LTS shipped with a packaging oversight that caused video and audio files to display blank thumbnails in the file manager when using the Default (minimal) install option. The missing packages — gst-audio-thumbnailer and gst-video-thumbnailer — were accidentally omitted from the minimal install metapackage but were present in the Extended selection install. Ubuntu 26.04 replaced older Totem-based thumbnailers with newer Rust-based ones built on GStreamer and Glycin, which is why the metapackage needed updating. A stable-release update (SRU) was issued and began rolling out in late June. Users still seeing blank icons can manually install the packages via apt.

Canonical becomes Gold Sponsor of Trifecta Tech Foundation

Canonical has become a Gold Sponsor of the Trifecta Tech Foundation, committing €40,000/year to support the development of memory-safe system utilities written in Rust. The collaboration builds on prior co-sponsorship of sudo-rs, which became the default in Ubuntu 26.04 LTS. The next phase focuses on adopting ntpd-rs as the default time synchronization client and server in Ubuntu, targeting testing in Ubuntu 26.10 and default status in Ubuntu 27.04. Funded work includes gpsd IP socket support, multi-threading for NTP servers, multi-homed server support, AppArmor/seccomp profiles, and gPTP support for connected vehicle deployments.

Canonical First Gold Sponsor Of Trifecta Tech For Building More Infrastructure In Rust

Canonical has become the first gold sponsor of the Trifecta Tech Foundation, committing €40,000/year to support the development of memory-safe system utilities written in Rust. Building on prior collaboration like the Rust-based sudo rewrite, the next focus is ntpd-rs, a Rust implementation of an NTP time synchronization client and server. The plan is to test ntpd-rs in Ubuntu 26.10 and make it the default in Ubuntu 27.04. The Trifecta Tech Foundation also counts AWS and Google as silver sponsors.

Rust Coreutils cp Ended Up Breaking Ubuntu Image Builds With Latest Incompatibility

A bug in the Rust Coreutils implementation of the cp command caused Ubuntu image builds to fail during live media ISO construction. The issue stemmed from incorrect handling of the -L argument. While a workaround was suggested (modifying the build script to avoid the problematic flag combination), Ubuntu ultimately reverted cp back to the GNU Coreutils version. A fix has been proposed upstream to the uutils/coreutils project but has not yet been merged. This is the latest in a series of compatibility issues discovered since Ubuntu 25.10 transitioned to Rust Coreutils.
