Python Debugger Extensions: cannot install but no error? Follow

Hi,

I use "PyCharm 2022.1 (Professional Edition)" on a Debian 11.3 (Bullseye). When I click on debug I get the notification saying:

Python Debugger Extensions Available

Cython extension speeds up Python debugging

Install | How does it work

Until recently (maybe when I updated Debian?) I had used the Cython extension without problems.

Now I click on Install, I don't see any error but the next time that I click on debug it shows the notification again.

If I go to Help - > Show Log I see:

If I execute the command displayed in the logs:

carles@pinux:~$ /usr/bin/python3.9 /home/carles/bin/pycharm-2019.2.3/plugins/python/helpers/pydev/setup_cython.py build_ext --build-lib /home/carles/.cache/JetBrains/PyCharm2022.1/cythonExtensions --build-temp /home/carles/.cache/JetBrains/PyCharm2022.1/cythonExtensions/build
running build_ext
running build_ext
running build_ext
carles@pinux:~$ 

Any idea on what's failing, why the popup is showed again and again? I prefer to make sure that the extensions are installed rather than disable them via PYDEVD_USE_CYTHON=NO

Thank you very much,
