Ubuntu Restricted Extras is the first package that most people install after a new installation of Ubuntu or any Ubuntu based Linux distro. You have just completed a new Ubuntu or Ubuntu based distro such as Elementary OS and needs to install restricted extras.

This article only talks about “ubuntu-restricted-extras”, but after running apt-get with other package names you will notice the same error. Hence it does not only apply to Ubuntu Restricted Extras and can be used to fix this on other packages as well.

Opening the terminal and running the command below produces “E: Unable to locate Ubuntu-restricted-extras” same will it be for other packages.

$ sudo apt-get install ubuntu-restricted-extras
[sudo] password for enock:
