Do you have some advice?

Hi,
for Ubuntu 20.04 the current Python version is still 3.8.x
If you are using Python 3.9 you have to also install all dependencies in regards to Python 3.9. For using pip that would mean that you have to also install and use pip3.9.

Could you please execute pip --version and pip3 --version to see what is configured on your system?

If you can I would suggest you run tlpui with Python 3.8 until 3.9/3.10 is set to be the new standard version.

Kind regards
