How to install CLion on Ubuntu 24.04

In this guide, we'll walk you through the process of installing CLion on Ubuntu 24.04. CLion is a powerful, cross-platform IDE for C and C++ development, offering a rich set of features to enhance your coding experience.

What is CLion?

CLion, developed by JetBrains, is an Integrated Development Environment (IDE) specifically designed for C and C++ programming. It offers intelligent code assistance, a powerful debugger, and seamless integration with various build systems and version control tools. Whether you're a beginner or an experienced developer, CLion can significantly boost your productivity.


Before we begin, ensure that your Ubuntu 24.04 system is up-to-date. It's also helpful to have a basic understanding of terminal commands.

Installation Steps

We'll be using Flatpak to install CLion. Flatpak is a next-generation technology for building and distributing desktop applications on Linux. Here's why we're using Flatpak:

  • It allows for easy installation and updates of applications
  • It provides better security through sandboxing
  • It ensures consistency across different Linux distributions

Let's get started with the installation process:

1. Install Required Packages

First, we'll install Flatpak and other necessary packages. Open your terminal and run the following command:

sudo apt install clang* g++ build-essential default-jdk flatpak

This command installs Clang (a C language family frontend for LLVM), G++ (the GNU C++ compiler), build-essential (a reference for all the packages needed to compile a Debian package), the default Java Development Kit, and Flatpak.

2. Add Flathub Repository

Next, we'll add the Flathub repository, which hosts a large collection of Flatpak applications:

sudo flatpak remote-add --if-not-exists flathub

This command adds the Flathub repository to your system if it doesn't already exist.

3. Install CLion

Now, we can install CLion using Flatpak:

sudo flatpak install flathub com.jetbrains.CLion

This command will download and install CLion on your system. Follow the prompts to complete the installation.

Launching CLion

After installation, you can launch CLion from your applications menu or by typing 'CLion' in the Activities overview. The first time you launch CLion, it may take a few moments to set up.

Troubleshooting Tips

If you encounter any issues during installation or while using CLion, consider the following tips:

  • Ensure your system is up-to-date by running sudo apt update && sudo apt upgrade before installation
  • If CLion doesn't launch, try running it from the terminal to see any error messages
  • Check the JetBrains support forums for solutions to common issues

By following this guide, you should now have CLion installed on your Ubuntu 24.04 system. Happy coding!
