I have installed clean Ubuntu MATE 18.04 LTS 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
/usr/bin/scilab-bin: error while loading shared libraries: libjava.so: cannot open shared object file: No such file or directory
so it can't find Java. I reported bug 1762999 about this problem.
I checked existence of libjava.so
:
$ dpkg -S libjava.so
openjdk-11-jre-headless:amd64: /usr/lib/jvm/java-11-openjdk-amd64/lib/libjava.so
so it is in place.
What should I do to get Scilab 6.0.1 working on Ubuntu 18.04 LTS?

* Repository-based method (Scilab itself and ATOMS will not work)
Update 2020-12-07. Nowadays Scilab is broken again as indicated in bug 1884277.
* Binary download method (fully-functional, seems to be really recommended)
So if you need fully-functional Scilab you should remove deb-packaged version with
and use latest binary archive 6.1.0 from official site and run the commands below (download, extract, add to PATH, set shortcuts and MIME-association):
The ATOMS and other components will work as expected. Do not forget to install
build-essential
package to run Xcos Modelica simulations.* AppImage download method (fully-functional)
We need to download the latest release from corresponding page or manually:
and then add it to PATH with
As the result you will get Scilab working. But there is no MIME associations (yet).
If you want to get Scilab 5.5.2 working on Ubuntu 18.04.1 LTS see other answer. But be careful with
libcurl4
removal!
