Install Kotlin Compiler on Debian 9

In this tutorial, we will show you how to install Kotlin Compiler on Debian 9. For those of you who didn’t know, Kotlin is a new statically typed language from JetBrains. JetBrains is famous for its popular Java IDE IntelliJ. Kotlin was recently open-sourced and the compiler was made accessible through Github. This article will reveal the steps necessary to build and install the compiler and run a program.

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. I will show you the step-by-step installation of the Kotlin Compiler on a Debian 9 (Stretch) server.


  • A server running one of the following operating systems: Debian 9 (Stretch).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
