Scilab cannot create Scilab Java Main-Class (we have not been able to find the main Scilab class. Check if the Scilab and thirdparty packages are available).
i tried reinstalling it and reinstalling java but still doesn't work
I have encountered the same problem. After googling I found out that this bug was fixed in Scilab 6.0.2.
You can download it here:
https://www.scilab.org/download/6.0.2
Current version of Scilab, that you can get from
sudo apt-get scilab
is 6.0.1 (for me scilab-cli was working, but GUI was not)
Currently Scilab 6.0.2 works in GUI mode and CLI under Ubuntu 18.04.4 LTS. XCOS works too.
It is a little bit laggy after start, but it might be my setup.
