How to Upgrade to Ubuntu Unity 24.04 LTS
Method 1: Using the Terminal (Command Line – Recommended)
Follow these steps for a safe terminal upgrade:
- Open your terminal.

Method 2: Using the Update Manager (GUI)
Ubuntu Unity includes a graphical upgrade option through the Update Manager:
- Open Update Manager from your applications menu or dash.
- Ensure all current updates are installed. Reboot if prompted.
- The Update Manager should detect the new release and prompt you: “New Ubuntu Unity release ‘24.04’ is available.”
- Click Upgrade and follow the on-screen instructions.
