Important: Before you proceed to install Ubuntu-restricted extras on your system, take note of the following:
- All software provided by the Ubuntu restricted extras meta-package is not free, which implies that the licensing requirements of such software do not meet the Ubuntu main component license policy.
- Also, ensure that you verify your rights to use any of the non-free software and adhere to the licensing terms of the copyright holder.
- Additionally, non-free software is usually not supported and can’t be fixed or updated, therefore, use it at your own risk.
Enable Multiverse Repository in Ubuntu
To install the restricted extras on Ubuntu, you need to enable the Multiverse Repository (which provides non-open-source software to users) on your Ubuntu system.
Run the following command to enable the multiverse repository: if you are prompted for a password, enter a valid one to proceed:
$ sudo add-apt-repository multiverse
If you prefer GUI, you can enable Multiverse Repository by clicking on Activities, then search for Software & Updates and open it.
The first or default tab, “Ubuntu Software” displays a list of repositories, or “channels“. Look for the option Multiverse (software restricted by copyright or legal issues) in the list and check it as highlighted in the next screenshot.
The system will prompt you to enter your user password to continue. Enter a valid password and click “Authenticate” to proceed.
Next, the system might also prompt you to choose a download server. Select a server in your location or nearby. Alternatively, you can click “Select Best Server” so that the system performs a few tests to select the best server. Then, to proceed, click “Choose Server” and input your password.
Once you try to close the Software & Updates application, the system will prompt you to refresh the package cache (similar to running the “sudo apt update” or “sudo apt-get update” command).
This step will add information about packages in the just-enabled repository to the local package index. Click Reload to proceed.
