Shadowfetch Linux 2.1.4 «Umbra»

Documentation

17 guides, covering installation, verification, hardware and Secure Boot, local AI tools, the security model, the known issues and the release history. Each page separates what the system does today from what is planned.

Get it running

From nothing installed to a working desktop.

  • Overview/

    What Shadowfetch Linux is: a private, AI-ready creative workstation built on Debian testing with KDE Plasma 6.

  • Screenshots/screenshots

    The desktop, the first-boot Welcome app, local AI tools and Control Center, as they ship.

  • Download/download

    The ISO, its exact size, the checksum and signature, resumable mirrors, and how to write it to a USB stick.

  • Verify/verify

    Confirm the SHA-256 checksum and the GPG signature on Linux, macOS or Windows before you install.

  • Install/install

    Boot the ISO, click through Calamares, reboot - about fifteen minutes, plus the first-boot notes.

  • APT repository/apt

    The signed repository (suite umbra, component main, amd64) for adding Shadowfetch packages to an existing Debian system.

  • Local AI/local-ai

    Optional on-machine models. Nothing phones home. Ordinary desktop use is complete without them.

  • Local AI benchmarks/benchmarks

    Measured tokens-per-second and VRAM fit on the studio RTX 5060 Ti (16 GB).

Hardware and boot

What it runs on, and the one firmware setting that stops it.

  • Hardware notes/hardware

    64-bit Intel and AMD requirements, RAM and disk headroom, NVIDIA and hybrid laptops, peripherals and virtual machines.

  • Secure Boot/secure-boot

    The installer is not signed by a Microsoft-trusted shim, so Secure Boot must be off. What that costs and how to do it safely.

Know the limits

Read this before installing on a machine you depend on.

  • Security model/security

    What is inherited from Debian, what Shadowfetch adds, what it does not collect, and the current caveats.

  • Known issues/known-issues

    The honest caveats: Secure Boot is unsigned, Debian testing moves, NVIDIA varies, local AI needs headroom.

  • Roadmap/roadmap

    What is shipping now versus what is planned, in stages. Dates are targets, not promises.

Reference

Answers, history, licensing.

  • FAQ/faq

    Direct answers on the Debian relationship, who it suits, NVIDIA, whether local AI phones home, and verifying the ISO.

  • Changelog/changelog

    The release history, and what changed in each one.

  • Licensing & source/licensing

    Upstream licenses, the license Shadowfetch's own components carry, and the written offer for corresponding source.

  • Support the project/donate

    Shadowfetch Linux is free and stays free. There is a tip jar, with no tiers, perks or gated features.
