DSHD 0.2.2-rc.1.3: Linux packages, signed releases, SBOM and provenance

[openviewmobile]

DSHD for Linux 0.2.2-rc.1.3 is available.

This is an independent, downstream Linux packaging project for the official DeepSeek Harness Desktop. It is not an official DeepSeek release and does not modify the agent core.

What is in this RC

• AppImage, deb, rpm and Flatpak for x86_64 and aarch64
• APT and DNF repositories (x86_64, GitHub Pages)
• Detached GPG signatures, SHA256SUMS, SPDX SBOM and GitHub build provenance
• Local DOCX/XLSX/PPTX → PDF through the bundled WASM engine
• CI-built and signed by GitHub Actions

Download

# Debian / Ubuntu
sudo install -d -m 0755 /etc/apt/keyrings
curl -fsSL https://openviewmobile.github.io/dshd-linux/key.asc \
  | sudo gpg --dearmor -o /etc/apt/keyrings/dshd-linux.gpg
echo "deb [signed-by=/etc/apt/keyrings/dshd-linux.gpg] https://openviewmobile.github.io/dshd-linux/apt stable main" \
  | sudo tee /etc/apt/sources.list.d/dshd-linux.list
sudo apt update && sudo apt install deepseek-harness

# Fedora / RHEL family
sudo curl -fsSL https://openviewmobile.github.io/dshd-linux/dshd-linux.repo \
  -o /etc/yum.repos.d/dshd-linux.repo
sudo dnf install deepseek-harness

For AppImage, download the asset and run chmod +x; for Flatpak use flatpak install --user --bundle.

Current limitations

• RC, not stable.
• Physical Wayland/KDE/GNOME testing is still pending.
• The AppImage update feed exists, but a complete A→B update acceptance is still pending.
• Flathub, AUR, Snap and OBS are not published as service builds.
• The unsigned filename suffix means no platform code-signing certificate; the files still have GPG signatures and checksums.

Feedback wanted

Please reply with:

• distribution + version
• package format
• X11 or Wayland
• exact error/log if installation fails

I am especially interested in Debian/Fedora/Arch packaging feedback, Wayland behavior, and whether the apt/dnf repositories are useful.
