The IntelliJ IDEA is an open-source IDE (Integrated Development Environment) for developing Java applications. It is developed and maintained by Jetbrains, a company also popular for developing PyCharm IDE. It's estimated that over 70% of Java developers prefer IntelliJ IDE over other IDEs like Eclipse.
In this guide, we will walk you through various ways to install IntelliJ IDEA on Ubuntu 20.04 LTS. At the time of writing this guide, the latest version of IntelliJ is IntelliJ 2020.2.
IntelliJ comes in 3 different Editions:
- The IntelliJ IDEA Community Edition
- IntelliJ IDEA Ultimate Edition ( A paid version with add-on features)
- IntelliJ IDEA Educational ( An ultimate Edition but free for students and faculty members)
Prerequisites
Before installing IntelliJ IDE, ensure that you have Java installed on Ubuntu 20.04 system. Also, ensure that you have a stable internet connection to install all the required packages.
1) Install IntelliJ using Ubuntu Software Center
This is the most recommended way of installing the IntelliJ IDE on Ubuntu. It's simple and fast. All you need to do is to launch Ubuntu Software Center and search for IntelliJ IDE as shown below. As expected, the three editions will be listed. Select your preferred edition by clicking on it.
Here, we have decided to select the Community Edition which is the free version.

In the next step, click the 'Install' button to begin the installation process. With a stable internet connection, this should take a couple of minutes to complete.

2) Install IntelliJ on Ubuntu using snap
Snap packages are universal prebuilt software packages that ship with libraries and dependencies required by the software package. They are distribution-agnostic and can be installed on any major Linux distribution. Snaps are popular as they do not require any dependencies during installation, thus making the installation process smooth and error-free.
For Ubuntu 18.04 and 20.04, Snap comes already enabled. Other distros that come with snap enabled also include KDE Neon, and Solus 3 and later versions.
To install the Community edition, execute the following command:
$ sudo snap install intellij-idea-community --classic
For the Ultimate Edition, run:
$ sudo snap install intellij-idea-ultimate --classic
And finally, for the Educational version, invoke the command:
$ sudo snap install intellij-idea-educational --classic
This should take a few minutes and should proceed without a hitch.
3) Install IntelliJ using flatpak
Just like snaps, flatpak is yet another universal software packaging format that makes it easy to install software applications without having t0 worry about dependencies.
As with snap, you must first ensure that flatpak is enabled on your Ubuntu system. Next head over to the Flathub site - an AppStore for flatpaks - and search for IntelliJ IDE as shown.

Click on the 'Install' button to download the flatpak package. Once downloaded, head over to the download directory and run the command below to install IntelliJ.
$ sudo flatpak install com.jetbrains.IntelliJ-IDEA-Community.flatpakref
4) Install IntelliJ from unofficial PPA
To install IntelliJ on Ubuntu and other Ubuntu variants such as Mint, Elementary Os and Zorin, you can use an unofficial PPA that is developed and maintained by Marcel Kapfer. This works on Ubuntu 16.04 and later versions and other distros based on them.
To install IntelliJ from the unofficial PPA, run:
$ sudo add-apt-repository ppa:mmk2410/intellij-idea
$ sudo apt-get update
$ sudo apt install intellij-idea-community
NOTE: You can only get the community edition using the PPA and not other editions.
5) Install IntelliJ using Ubuntu make (For Ubuntu only)
In case you didn't know, Ubuntu make is a command-line tool that allows users to install the latest versions of IDEs such as Pycharm and Android Studio. Thankfully, IntelliJ is one of the supported IDEs. But first you need to install Ubuntu Make on your system.
To do so, first, run the command:
$ sudo apt install ubuntu-make
To install IntelliJ IDEA community version, run the command
$ umake ide idea
For the ultimate version, execute:
$ umake ide idea-ultimate
This takes some time, and some patience will do.
Launching IntelliJ
To launch IntelliJ on Ubuntu, use the application to search for it as shown. Then click on the IntelliJ icon.

Next, accept the license agreement by checking off the checkbox on the far left corner and click on the 'Continue' button.

In the next step, you can choose to send anonymous statistics on the usage of IntelliJ IDE to developers or not. Select your preferred choice.

Thereafter, IntelliJ will be initialized as shown. Give it about 2-3 minutes.

Eventually, you will get the welcome pane shown. Click on the 'New Project' button to begin creating your Java applications.
