[Python] Problems with Tkinter libraries dependencies in a codespace on Ubuntu 22.04.1 (linux)

Issue with Testing tkinter in a Headless Environment

What I Am Trying to Do


I am trying to test if tkinter is installed and working by running the following command in the terminal:

python3 -m tkinter


I've installed tkinter dependencies (e.g., sudo apt-get install python3-tk) and verified your Python version is 3.1

Error Message When I run the command, I get the following error:

File "<frozen runpy>", line 198, in _run_module_as_main
