Prerequisites: What You Need to Get Started

Before diving into the installation of IntelliJ IDEA Ultimate on Ubuntu 24.04, make sure you have the following prerequisites:

• Ubuntu 24.04: Ensure that your operating system is fully updated. You can check for updates by running the command:
  bash
  sudo apt update && sudo apt upgrade

• Java Development Kit (JDK): IntelliJ IDEA requires a Java Development Kit to function. Ideally, you should install the latest version of the JDK, as it enhances compatibility and performance. You can check if JDK is installed by running:

  If it’s not installed, you can do so by following the command:

Step-by-Step installation guide

1. Downloading IntelliJ IDEA Ultimate

The first step in the installation process is downloading IntelliJ IDEA Ultimate from the official JetBrains website. Here’s how:

1. Navigate to the JetBrains download page.
2. Choose the Ultimate version.
3. Click the “Download” button.

Your browser will start downloading a .tar.gz archive file containing the installation files.

2. Extracting the Downloaded File

Once the download is complete, you’ll need to extract the contents of the downloaded archive. You can do this by following these steps:

1. Open a terminal window (you can do this by searching for “Terminal” in your application menu).

2. Navigate to the directory where your downloaded file resides. For example:
   bash
   cd ~/Downloads

3. Extract the downloaded file using the following command:
   bash
   tar -xzf ideaIU-*.tar.gz

3. Moving to the Installation Directory

To organize your applications better, it’s a good practice to move the extracted folder to a dedicated location. You can follow these steps:

1. Create a new directory for JetBrains applications:
   bash
   sudo mkdir /opt/jetbrains

2. Move the extracted IntelliJ directory to this new location:
   bash
   sudo mv idea-IU-* /opt/jetbrains/idea

4. Starting IntelliJ IDEA Ultimate

To start IntelliJ IDEA Ultimate, you can run it from the terminal:

1. Run the following command:
   bash
   /opt/jetbrains/idea/bin/idea.sh

   This will launch the IDE for the first time. You may want to create a desktop entry for easier access in the future.

5. Creating a Desktop Entry (Optional)

Creating a desktop entry means you can easily open IntelliJ IDEA from your application menu. Here’s how:

1. Create a new desktop entry file:
   bash
   sudo nano /usr/share/applications/jetbrains-idea.desktop

2. Paste the following content into the file:
   ini
   [Desktop Entry]
   Version=1.0
   Type=Application
   Name=IntelliJ IDEA Ultimate
   Exec=/opt/jetbrains/idea/bin/idea.sh
   Icon=/opt/jetbrains/idea/bin/idea.png
   Categories=Development;IDE;
   Terminal=false

3. Save and exit by pressing CTRL + O, followed by CTRL + X.

Common Issues and Troubleshooting

Despite the user-friendly interface, users may still encounter issues during installation or usage. Here are some common problems and their solutions:
