cause Running on a headless server or without a display.

fix

Use a virtual display (e.g., Xvfb) or run locally with a GUI.

gotcha plink requires a Tkinter-capable Python installation (tkinter must be importable). ↓

fix Install Tkinter via your system package manager (e.g., python3-tk on Ubuntu) or use a Python distribution that bundles Tkinter.

gotcha plink's GUI does not work in headless environments (no display server). ↓

fix Run on a desktop environment or use Xvfb for headless testing, but GUI interaction is required.
