Run JNLP Files on Ubuntu

1sudo apt install icedtea-netx -y

icedtea-netx requires openjdk-8-jre and openjdk-8-jre-headless as dependencies so it’ll install JRE (Java Runtime Environment) for you as well if you don’t have that already.

• JNLP is Java Network Launching Protocol
• icdeatea-netx is Netx implementation of JNLP
• icedtea-plugin is web browser plugin to execute Java applets. No longer available in Ubuntu (20.04)
