How To Install Scala on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Scala on Ubuntu 20.04 LTS. For those of you who didn’t know, Scala is a relatively modern high-level language that supports object-oriented programming and functional programming capabilities. Scala’s static types help avoid bugs in complex applications, and its JVM and JavaScript runtimes let you build high-performance systems with easy access to huge ecosystems of libraries.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges.
