How to install proprietary media codecs and font on Ubuntu

Ubuntu does not include many multimedia codecs and fonts by default. This is due to licensing and legal restrictions. These codecs are necessary for playing formats like DVD, MP3, QuickTime, and Windows Media.

During the Ubuntu installation, you can choose to install these codecs. This option is available under “Install third-party software for graphics and Wi-Fi hardware and additional media formats.” If you miss this option, your system will lack the ability to play these formats.

You can install these codecs later using the apt package manager. The package ubuntu-restricted-extras includes the needed codecs and other proprietary software, such as Microsoft fonts. This package allows your system to support various multimedia formats.

1. Open the terminal.
2. Update the package list using apt.

   $ sudo apt update
   [sudo] password for user:
