FunOS 24.04.4 is the latest point release in the 24.04 LTS series. It is based on Ubuntu 24.04.4 LTS (Noble Numbat) and includes updated packages, improved hardware support through the HWE stack, a newer Linux kernel, updated Mesa graphics drivers, and various stability improvements.

If you are currently using FunOS 24.04.3, you do not need to reinstall the system. You can safely upgrade your existing installation by following the steps below.

Step 1: Open a Terminal

The upgrade process is performed using the Terminal.

There are several ways to open it:

• Click the Menu button in the lower-left corner of the screen, then select Terminal
• Click the Terminal icon in the Tray
• Press Ctrl + Alt + T on your keyboard

Once the Terminal window opens, continue to the next step.

Step 2: Update the Package List

First, refresh the package index to make sure your system knows about the latest available updates.

Run the following command:

sudo apt update

Enter your password when prompted.
This command does not upgrade anything yet — it only updates the list of available packages.

Step 3: Upgrade the System

Next, upgrade all installed packages to the newest versions available in the Ubuntu Noble repositories.

Run:

sudo apt upgrade

If the system asks for confirmation, type:

Y

then press Enter.

This step ensures your FunOS 24.04.3 installation is fully updated before applying the FunOS-specific upgrade script.

Step 4: Download the Latest funos-update Script

FunOS uses a dedicated upgrade script called funos-update to apply distribution-specific changes and updates.

Download the latest version of the script from the official FunOS GitHub repository:

wget https://raw.githubusercontent.com/funos-linux/funos-updates/main/ubuntu/24.04/funos-update

After downloading, move it to /usr/bin/ so it can be executed system-wide:

sudo mv funos-update /usr/bin/

This ensures you are using the most recent version of the upgrade script.

Step 5: Make the Script Executable

Now give the script permission to run:

sudo chmod +x /usr/bin/funos-update

This command makes the file executable.

Step 6: Run the funos-update Script

Now execute the upgrade script:

sudo funos-update

If the system asks for confirmation, type:

Y

The script will:

• Apply FunOS 24.04.4 specific updates
• Adjust system configurations if necessary

Wait until the process completes. Do not close the Terminal during this step.

Step 7: Remove Unused Packages

After upgrading, it is recommended to clean up unused packages to keep the system tidy.

Run:

sudo apt autoremove

This removes unnecessary dependencies and old packages that are no longer required.

Step 8: Restart Your System

To complete the upgrade process, reboot your system:

sudo reboot now

Alternatively:

Go to Menu > Log Out > Reboot

Wait for the system to restart.

Step 9: Log Back In

Once the system has restarted, log back into your desktop session as usual.

Your system should now be running FunOS 24.04.4.
