Prerequisites
NetBeans assumes that the appropriate version of JDK is installed on the System. NetBeans 11 needs at least JDK 8 to continue the installation. You can follow How To Install Java 14 On Ubuntu, How To Install OpenJDK 14 On Ubuntu, or How To Install Java 8 On Ubuntu to install the most recent version of JDK on your Windows system. The installer threw an error (java.lang.NoClassDefFoundError: java/util/jar/Pack200) with Java 14, hence I have to switch back to Java 8 on my system path.
