[Scilab-users] Problem starting scilab on Ubuntu 18.04

Good afternoon,

I'm running Ubuntu 18.04 and I just installed scilab using

$ sudo apt-get install scilab

It looks to be version 6.0.1-7.  I can run the CLI but when I try to run
the GUI using

$ scilab

I get an error (show below). Any pointers? I tried Googling but didn't see
anything related to this.

Thanks!

Jeff
