Open WebUI : Install2025/09/30

	Install Open WebUI which allows you to run LLM on Web UI. Open WebUI can be easily installed with pip3, but as of September 2025, the default version of Debian 13, Python 3.13, and related modules do not all support the versions required by Open WebUI. Therefore, in this example, we will start it in a container.
[1]	Install Podman, refer to here.
[2]	Install Ollama, refer to here.
[3]	Pull and start the Open WebUI container image.
