Cupcarbon x Ubuntu launch error

[Patrick Agr]

Hi there, working towards PhD in LabSTICC for future publications with IoT simulated in CupCarbon

I've got a dual-boot machine (Ubuntu 20.04 / Windows) and even though I have succeeded tp launch CupCarbon on Windows, I would like for external codes implementation to install it on Ubuntu.

I've tried either the basic launch ("java -jar cupcarbon.jar") or with Eclipse, but nothing had worked.

Before asking of course, I've checked my environnement variable JAVA_HOME and, java version to make sure it was the same as my working dual on Windows. (java 1.8.0.22)

I get from terminal :

Welcome to CupCarbon Version Twin IoT 6.5

Is there anything I can do to make it work ? Thanks a lot !
