Running Dekupeo on Linux

Dekupeo is distributed as a portable AppImage, which means no installation is required. It should run on most modern Linux distributions (Ubuntu 22.04+, Debian 11+, Fedora 36+, etc.).

1. Make executable & Run

After downloading, you need to grant execution permission to the file. You can do this via your file manager (Right click → Properties → Permissions → Allow executing file as program) or via terminal:

# Make executable (one-time)
chmod +x Dekupeo-*.AppImage

# Run the application
./Dekupeo-*.AppImage

2. FUSE Requirements

AppImages require FUSE (Filesystem in Userspace) to run. Most modern distributions like Ubuntu 22.04 come with it pre-installed. However, on some newer systems (like Ubuntu 24.04), if the application fails to start, you might need to install libfuse2 manually:

sudo apt update
sudo apt install -y libfuse2

3. Serial Port Permissions

If you are connecting your laser via USB and find that Dekupeo cannot access the serial port (usually /dev/ttyUSB0 or /dev/ttyACM0), you likely need to add your user to the dialout group:

sudo usermod -aG dialout $USER

Note: You must log out and log back in (or restart your computer) for this change to take effect.
