# Install GitHub Copilot AppImage in WSL

This guide installs the GitHub Copilot Linux AppImage inside WSL and avoids the common AppImage FUSE issue on Ubuntu 24.04.

## Prerequisites

- WSL2 with WSLg enabled
- The AppImage downloaded on Windows, for example:

```bash
/mnt/c/Users/<windows-user>/Downloads/GitHub-Copilot-linux-x64.AppImage
```

## Install

Set the path to your downloaded AppImage:

```bash
APPIMAGE="/mnt/c/Users/<windows-user>/Downloads/GitHub-Copilot-linux-x64.AppImage"
INSTALL_DIR="$HOME/.local/opt/github-copilot"
```

Create install directories and copy the AppImage:

```bash
mkdir -p "$INSTALL_DIR" "$HOME/.local/bin" "$HOME/.local/share/applications" "$HOME/.local/share/icons/hicolor/512x512/apps"
cp "$APPIMAGE" "$INSTALL_DIR/GitHub-Copilot.AppImage"
chmod +x "$INSTALL_DIR/GitHub-Copilot.AppImage"
```

Extract the AppImage:

```bash
TMP_DIR="$(mktemp -d)"
cd "$TMP_DIR"
"$INSTALL_DIR/GitHub-Copilot.AppImage" --appimage-extract
rm -rf "$INSTALL_DIR/app"
mv squashfs-root "$INSTALL_DIR/app"
rm "$INSTALL_DIR/GitHub-Copilot.AppImage"
```

Create the command wrapper:

```bash
tee "$HOME/.local/bin/github-copilot" >/dev/null <<'EOF'
#!/usr/bin/env bash
set -euo pipefail

exec "$HOME/.local/opt/github-copilot/app/AppRun" "$@"
EOF

chmod +x "$HOME/.local/bin/github-copilot"
```

Install the icon and desktop launcher:

```bash
cp "$INSTALL_DIR/app/usr/lib/GitHub Copilot/icons/icon.png" \
  "$HOME/.local/share/icons/hicolor/512x512/apps/github-copilot.png"

tee "$HOME/.local/share/applications/github-copilot.desktop" >/dev/null <<EOF
[Desktop Entry]
Type=Application
Name=GitHub Copilot
Comment=Tauri Copilot Application
Exec=$HOME/.local/bin/github-copilot %u
Icon=github-copilot
Terminal=false
StartupWMClass=github
Categories=Development;
MimeType=x-scheme-handler/github-app;x-scheme-handler/ghapp;x-scheme-handler/gh;
EOF
```

Refresh desktop metadata:

```bash
update-desktop-database "$HOME/.local/share/applications" 2>/dev/null || true
gtk-update-icon-cache -q "$HOME/.local/share/icons/hicolor" 2>/dev/null || true
```

## Run

```bash
github-copilot
```

You can also open **GitHub Copilot** from the WSLg app menu.

## Notes

- Replace `<windows-user>` with your Windows username.
- Make sure `~/.local/bin` is on your `PATH`.
- This extraction method does not require `sudo` or `libfuse2`.
