Claude Desktop for Linux

This project provides build scripts to run Claude Desktop natively on Linux systems. It repackages the official Windows application for Debian-based distributions, producing either .deb packages or AppImages.

Note: This is an unofficial build script. For official support, please visit Anthropic's website. For issues with the build script or Linux implementation, please open an issue in this repository.

Features

• Native Linux Support: Run Claude Desktop without virtualization or Wine
• MCP Support: Full Model Context Protocol integration

Configuration file location: ~/.config/Claude/claude_desktop_config.json

• System Integration:
• Global hotkey support (Ctrl+Alt+Space) - works on X11 and Wayland (via XWayland)
• System tray integration
• Desktop environment integration

Installation

Using Pre-built Releases

Download the latest .deb or .AppImage from the Releases page.

Building from Source

Prerequisites

• Debian-based Linux distribution (Debian, Ubuntu, Linux Mint, MX Linux, etc.)
• Git
• Basic build tools (automatically installed by the script)

Build Instructions

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

# Build a .deb package (default)
./build.sh

# Build an AppImage
./build.sh --build appimage

# Build with custom options
./build.sh --build deb --clean no  # Keep intermediate files

# Build using a locally downloaded installer
# (useful when the bundled download URL is outdated)
./build.sh --exe /path/to/Claude-Setup.exe

Installing the Built Package

For .deb packages:

sudo dpkg -i ./claude-desktop_VERSION_ARCHITECTURE.deb

# If you encounter dependency issues:
sudo apt --fix-broken install

For AppImages:

# Make executable
chmod +x ./claude-desktop-*.AppImage

# Run directly
./claude-desktop-*.AppImage

# Or integrate with your system using Gear Lever

Note: AppImage login requires proper desktop integration. Use Gear Lever or manually install the provided .desktop file to ~/.local/share/applications/.

Automatic Updates: AppImages downloaded from GitHub releases include embedded update information and work seamlessly with Gear Lever for automatic updates. Locally-built AppImages can be manually configured for updates in Gear Lever.

Configuration

MCP Configuration

Model Context Protocol settings are stored in:

~/.config/Claude/claude_desktop_config.json

Environment Variables

Wayland Note: By default, Claude Desktop uses X11 mode (via XWayland) on Wayland sessions to ensure global hotkeys work. If you prefer native Wayland and don't need global hotkeys:

# One-time launch
CLAUDE_USE_WAYLAND=1 claude-desktop

# Or add to your environment permanently
export CLAUDE_USE_WAYLAND=1

Application Logs

Runtime logs are available at:

~/.cache/claude-desktop-debian/launcher.log

Uninstallation

For .deb packages:

# Remove package
sudo dpkg -r claude-desktop

# Remove package and configuration
sudo dpkg -P claude-desktop

For AppImages:

1. Delete the .AppImage file

2. Remove the .desktop file from ~/.local/share/applications/

3. If using Gear Lever, use its uninstall option

Remove user configuration (both formats):

rm -rf ~/.config/Claude

Troubleshooting

Window Scaling Issues

If the window doesn't scale correctly on first launch:

1. Right-click the Claude Desktop tray icon

2. Select "Quit" (do not force quit)

3. Restart the application

This allows the application to save display settings properly.

Global Hotkey Not Working (Wayland)

If the global hotkey (Ctrl+Alt+Space) doesn't work, ensure you're not running in native Wayland mode:

1. Check your logs at ~/.cache/claude-desktop-debian/launcher.log

2. Look for "Using X11 backend via XWayland" - this means hotkeys should work

3. If you see "Using native Wayland backend", unset CLAUDE_USE_WAYLAND or ensure it's not set to 1

Note: Native Wayland mode doesn't support global hotkeys due to Electron/Chromium limitations with XDG GlobalShortcuts Portal.

AppImage Sandbox Warning

AppImages run with --no-sandbox due to electron's chrome-sandbox requiring root privileges for unprivileged namespace creation. This is a known limitation of AppImage format with Electron applications.

For enhanced security, consider:

• Using the .deb package instead
• Running the AppImage within a separate sandbox (e.g., bubblewrap)
• Using Gear Lever's integrated AppImage management for better isolation

Technical Details

How It Works

Claude Desktop is an Electron application distributed for Windows. This project:

1. Downloads the official Windows installer

2. Extracts application resources

3. Replaces Windows-specific native modules with Linux-compatible implementations

4. Repackages as either:

• Debian package: Standard system package with full integration
• AppImage: Portable, self-contained executable

Build Process

The build script (build.sh) handles:

• Dependency checking and installation
• Resource extraction from Windows installer
• Icon processing for Linux desktop standards
• Native module replacement
• Package generation based on selected format

Automated Version Detection

A GitHub Actions workflow runs daily to check for new Claude Desktop releases:

1. Uses Playwright to resolve Anthropic's Cloudflare-protected download redirects

2. Compares resolved URLs with those in build.sh

3. If a new version is detected:

• Updates build.sh with new download URLs
• Creates a new release tag
• Triggers automated builds for both architectures

This ensures the repository stays up-to-date with official releases automatically.

Manual Updates

If you need to build with a specific version before the automation catches it:

1. Use a local installer: Download the latest installer from claude.ai/download and build with:

./build.sh --exe /path/to/Claude-Setup.exe

2. Update the URL: Modify the CLAUDE_DOWNLOAD_URL variables in build.sh.
