THIS IS AN UNOFFICIAL PKGBUILD FOR ARCH LINUX BASED SYSTEMS!

If you run into an issue with this build script, make an issue here. Don't bug Anthropic about it - they already have enough on their plates.

Claude Desktop for Linux (Arch PKGBUILD)

This project provides an Arch Linux PKGBUILD to install the Claude Desktop application. It was inspired by k3d3's claude-desktop-linux-flake and their Reddit post about running Claude Desktop natively on Linux.

Supports MCP! Location of the MCP-configuration file is: ~/.config/Claude/claude_desktop_config.json

Supports the Ctrl+Alt+Space popup!

Supports the Tray menu! (Screenshot of running on KDE)

Building & Installation (Arch Linux)

For Arch Linux and Arch-based distributions, you can build and install using the provided PKGBUILD:

# Clone this repository
git clone https://github.com/aaddrick/claude-desktop-arch.git
cd claude-desktop-arch

# Update checksums (needed once, or after PKGBUILD/install script changes)
updpkgsums

# Build and install the package
# This command automatically handles dependencies, builds, and installs
# Use makepkg -sci to automatically clean up build files afterwards
makepkg -si

The PKGBUILD will automatically:

• Detect your architecture (x86_64 or aarch64)
• Determine the latest application version
• Download the correct official Windows installer
• Check for and prompt to install required dependencies (using pacman)
• Extract application resources
• Apply Linux compatibility patches (native module stub, Wayland flags)
• Package Electron locally within the application
• Create and install an Arch Linux package (.pkg.tar.zst)

Uninstallation

If you installed the package using makepkg -si or pacman -U, you can uninstall it using pacman:

sudo pacman -R claude-desktop

To also remove user-specific configuration files (including MCP settings):

sudo pacman -Rns claude-desktop
# Or manually remove the config directory:
# rm -rf ~/.config/Claude

Troubleshooting

Window Scaling Issues

If your window isn't scaling correctly the first time or two you open the application, right-click on the claude-desktop panel (taskbar) icon and choose "Quit". When doing a safe shutdown like this, the application saves window state information to ~/.config/Claude/ which should resolve the issue on subsequent launches. Force quitting the application (e.g., via kill) will not trigger these state updates.

Application Fails to Launch (Sandbox Issues)

The PKGBUILD attempts to configure the Electron sandbox correctly by packaging Electron locally and setting SUID permissions on chrome-sandbox via the .install script. This should work in most cases.

However, if the application installs but fails to launch (you might see errors related to sandboxing or zygote processes in the terminal when running claude-desktop), you could try launching it with the --no-sandbox flag as a last resort:

claude-desktop --no-sandbox

If this works, you could make it permanent by editing the launcher script /usr/bin/claude-desktop, but this is strongly discouraged as it reduces security isolation. It's better to investigate why the sandbox isn't working (e.g., kernel settings like kernel.unprivileged_userns_clone, filesystem mount options like nosuid on /usr/lib).

Editing the launcher (Use with caution):

1. Open the launcher script with root privileges: sudo nano /usr/bin/claude-desktop
2. Locate the line near the end that executes Electron. It will look like this:

   "$ELECTRON_EXEC" "${ELECTRON_ARGS[@]}"

3. Modify that line by adding --no-sandbox immediately after "$ELECTRON_EXEC":

   # Before:
   # "$ELECTRON_EXEC" "${ELECTRON_ARGS[@]}"
   # After:
   "$ELECTRON_EXEC" --no-sandbox "${ELECTRON_ARGS[@]}"

4. Save the file (Ctrl+O in nano, then Enter) and exit (Ctrl+X in nano).

How it works (Arch PKGBUILD)

Claude Desktop is an Electron application packaged as a Windows executable. The PKGBUILD performs several key operations to make it work natively on Arch Linux:

1. Source Fetching: Downloads the official Windows installer (.exe) appropriate for the target architecture ($CARCH).
2. Version Detection: The pkgver() function extracts the version number from the downloaded installer's contents (specifically, the embedded .nupkg filename).
3. Build Process (build()):
   • Installs electron and asar locally using npm to ensure correct versions for packaging.
   • Extracts the Windows installer (.exe) using p7zip.
   • Extracts the application files from the embedded NuGet package (.nupkg).
   • Extracts icons using wrestool and icotool.
   • Unpacks the app.asar archive using the local asar tool.
   • Replaces the Windows-specific native module (claude-native) with a Linux-compatible JavaScript stub (in both app.asar.contents and app.asar.unpacked). This stub provides dummy functions for Windows APIs while keeping necessary parts like KeyboardKey.
   • Downloads and applies assets for the main window title bar fix from emsi/claude-desktop.
   • Repacks the modified app.asar.
4. Packaging (package()):
   • Installs the application files (app.asar, app.asar.unpacked) into /usr/lib/claude-desktop/.
   • Installs the locally built node_modules (containing Electron) into /usr/lib/claude-desktop/.
   • Installs icons into /usr/share/icons/hicolor/.
   • Creates a .desktop file in /usr/share/applications/ for menu integration.
   • Creates a launcher script /usr/bin/claude-desktop that:
     • Uses the packaged Electron executable.
     • Detects Wayland sessions and adds necessary flags (--enable-features=UseOzonePlatform,WaylandWindowDecorations --ozone-platform=wayland).
     • Changes to the application directory before launching.
5. Post-Install (claude-desktop.install):
   • Sets SUID permissions (chown root:root, chmod 4755) on the packaged chrome-sandbox executable (/usr/lib/claude-desktop/node_modules/electron/dist/chrome-sandbox) to allow the sandbox to function correctly.
   • Updates the desktop file database (update-desktop-database).

This process works because the core Claude Desktop application is largely cross-platform (being Electron-based). The main challenge is handling the Windows-specific native module and ensuring the Electron environment (including the sandbox) is set up correctly on Linux.
