I am trying to install Cytoscape on my Ubuntu machine and I get this error:

No suitable Java Virtual Machine could be found on your system. The version of the JVM must be at least 11.0 and at most 12. Please define INSTALL4J_JAVA_HOME to point to a suitable JVM.

Here is the output of java -version

openjdk version "9-internal" OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src) OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

I have no idea what is wrong.

you have openjdk 9 installed.. for Cytoscape you need to have at least openjdk 11 which you can install with sudo apt install opendjk-11-jdk-headless – kannzzmm2 Sep 05 '20 at 09:16
Seems my version of Ubuntu is too old, 16.04. Can it be installed by downloading from Java website? – Reza Sep 05 '20 at 09:30

Does this answer your question? How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE? Note: Here Java version doesn't really matter. From Oracle's site, you'll get an archive and the installation procedure would be same as in the answers on that question. Also, note that javaws is no longer available. You can skip commands including javaws. – Kulfy Sep 05 '20 at 09:36

Just that Oracle has changed its license. I can't download anything. – Reza Sep 05 '20 at 13:53
