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 have tried: – running from the cli – running from the launcher

the cli version works

have gone to the forums and checked for the different solutions – deleting the SCIHOME directory. – reinstalling Scilab. – reinstalling from different sources. – purging all the directories related to Scilab and reinstalling.

Answer

The Ubuntu package is broken. Please use the official .tar.gz distribution from Scilab site: https://www.scilab.org/download/6.1.0
