Hi! I'm having the following error. My kernel seems to start correctly but when I enter "Ctrl+Enter" in the Scilab notebook, I get this error:

I'm using Ubuntu 20.04. Let me know if I can provide any more details. Thank you

Hi @Acentelles, are you able to run /usr/bin/scilab-adv-cli directly without error? From the traceback it looks like it might not be functional: en able to find the main Scilab class. Check if the Scilab and thirdparty packages are available.

@Acentelles same here! Scilab gui not working but scilab cli working..
