I. Core Feature Additions and Optimizations

1.1 Linyaps

Linyaps is a software package management tool independently developed by deepin, designed to address long-standing issues in Linux software ecosystems such as dependency conflicts, fragmented distribution, and high security risks.

Based on mechanisms like User Namespace and CGroup, Linyaps provides a unified application runtime environment decoupled from the operating system. This environment includes libraries and dependencies commonly used by desktop applications such as Qt, supports multi-version coexistence, and implements a "one architecture, one build" model.

Currently, Linyaps supports major distributions including deepin, UOS, openEuler, and Ubuntu, and is compatible with AMD64, ARM64, and LoongArch platforms. It enables one-click conversion of deb, AppImage, and Flatpak formats into Linyaps packages. Applications can also be distributed globally through the standalone public Linyaps Store. As of the end of 2024, over 3,000 applications have been adapted.

KDE Gear 24.12.3 Apps Collection Rolls Out

Aurigo — Fri, 07 Mar 2025 07:10:30 +0000

KDE Gear 24.12.3 apps collection is now available for download with fixes for file handling, UI crashes, and more.

Today, exactly a month after its previous 24.12.2 release, KDE has rolled out the latest version of its app collection, KDE Gear 24.12.3, as the third (and last) update to the 24.12 series, focuses on enhancing performance, resolving bugs, and improving user experience.

This release mainly focuses on bug fixes to ensure stability across various applications. For example, KWwordQuiz, a general-purpose flash card app, has solved an issue that prevented files from being opened from the command line. At the same time, kio-extras now supports AFC filesystems on iPhone and iPad devices without a hitch.

Moreover, Okular, KDE’s universal document viewer, has successfully addressed crashes related to small background images in digital signing, making it far more reliable for document handling.

Beyond these highlights, you will find fixes for compilation errors, streamlined user interface tweaks, and performance enhancements in applications such as Calligra, Dolphin, Gwenview, Kdenlive, Konsole, and many more.

The developers have also updated translations across the board, ensuring that users who prefer non-English interfaces benefit from a polished and cohesive experience.

For more information, see the release notes. KDE Gear 24.12.3 apps collection tarballs can be downloaded from the source info page, as the full changelog provides a deeper dive into the update.

Lastly, most KDE Gear 24.12.3 apps will soon be available on Flathub and Snap Store. Rolling release distributions can expect the app collection in their respective distros’ repositories in the coming days and weeks.

How to use DeepSeek-R1 on deepin

Aurigo — Wed, 05 Mar 2025 10:20:21 +0000

I've been experimenting with deepin lately, and some time ago I discovered that deepin's own AI app (UOS AI) accesses the DeepSeek-R1 model. So I'll share a tutorial on how to use it.

Update UOS AI deepin 23: One-click update via Application Store. deepin 25 Preview: sudo apt update sudo apt install uos-ai deepin-modelhub uos-ai-rag

Pro Tip: First-time users will activate a free trial account post-installation.

After updating, open the Settings option in UOS AI, go to Model Configuration - Local Models, and select Embedding Plugin - Install/Update. You will be automatically redirected to the application store interface, where you can click Install/Update to complete the process.

Download & Install Model
Grab the pre-optimized DeepSeek-R1-1.5B GGUF .
Move the model to:
/home/[USERNAME]/.local/share/deepin-modelhub/models
Activate in UOS AI
Navigate: Settings → Model Configuration → Local Models → Select DeepSeek-R1-1.5B.

After completing the above configuration, you can use it directly in the software.
