# Ubuntu – How to get Scilab 6.0.1 working on Ubuntu 18.10

18.10javaopenjdkscilab

I have installed clean Ubuntu MATE 18.10 and installed Scilab from repository here with

sudo apt-get update
sudo apt-get install scilab


After installation I tried to launch it from GUI (Applications → Other → Scilab) – it does not start.
Then I tried to launch it from terminal with scilab command. Terminal output is as follows:

\$ scilab

So I reported bug 1798661 to the LaunchPad.

It seems that I need to get java.xml.bind from some package.
According to search on packages.ubuntu.com I need to install openjdk-11-jdk-headless package, but it does not have needed file in Ubuntu 18.10 Cosmic.

Note: I do not want to download and extract binary archive from Scilab web-site (but this is a workaround). I need the solution with deb-packages using APT.

What else should I try?

• Nowadays Scilab is ported to OpenJDK 11. So we have to install it with (if not installed before):

sudo apt-get install scilab


So we can use latest scilab package 6.0.1-7ubuntu1~18.10 as usual from GUI, but scilab-cli and scilab-adv-cli are now broken (it is new bug 1825037).

Note 1: Scilab color theme is incompatible with dark Gtk themes, so user should set light one (this is bug 1547561) such as Radiance or Radiant-MATE.

Note 2: Scilab ATOMS system is broken too (see bug 1765503) because of problems with HDF5.

To prevent this bugs we need to install binary version as written in my answer for Ubuntu 18.04 LTS .
