Distribution Release: Kubuntu 25.10 |
|
The Kubuntu project has announced the availability of Kubuntu 25.10. The new release runs Plasma 6.4, uses a Wayland session by default, and introduces Rust-based core utilities. "Here are three standout enhancements that Kubuntu 25.10 brings to your desktop, designed to make your workflow faster, more secure, and visually stunning: KDE Plasma 6.4, a refined and responsive desktop dive into the fifth feature release of Plasma 6, complete with Qt 6.8 and Frameworks 6.17.0. This update refines the desktop with smoother animations, improved widget customization, and better multi-monitor handling. It's a big win for productivity, letting you tailor your environment like never before while enjoying the stability of Ubuntu's core. Plasma Wayland as default session, say goodbye to legacy X11 limitations - Wayland is now the go-to session for superior graphics rendering, reduced latency, and enhanced security. With hardware-accelerated compositing baked in, you'll notice snappier video playback and app responsiveness. (X11 fans, no worries: it's still available via a simple package install.) This shift future-proofs your setup for the next era of Linux desktops. Rust-powered sudo-rs for safer system management leveraging Ubuntu's new memory-safe implementations, Kubuntu defaults to sudo-rs, a Rust-based re-implementation of sudo. " Additional details can be found in the release announcement. Download: kubuntu-25.10-desktop-amd64.iso (4,713MB, SHA256, signature, torrent, pkglist). |

Pie Box Enterprise Linux
Pie Box Enterprise Linux was a Linux distribution that was derived from the open source software made available by Red Hat, Inc. It was built from the source RPMs of Red Hat Enterprise Linux. Only a small number of packages are modified in order to remove Red Hat's trademarks from relevant images and to skip the RHN registration step immediately after installation. All other packages remain unchanged from those released by Red Hat and there are no packages added or removed. This results in a product that was fully compatible with Red Hat Enterprise Linux. The updates and repository service was very similar to the up2date service offered by Red Hat, Inc. It was a subscription-based service under which errata are distributed that have been compiled from source RPM packages that have been released by Red Hat, Inc.
Status: Discontinued
