Answer 1

Unable to locate package ubuntu-restricted-extras?
Make sure that all Ubuntu repositories are enabled.

Open a terminal and execute :

sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted

Now install the packages :

sudo apt-get update
sudo apt-get install ubuntu-restricted-extras  

Note :

Maybe the ttf-mscorefonts-installer lets the installation process hang, because the license agreement is hidden in the background. So make sure to accept the Microsoft license agreement.

Answer 2

Go to software sources and enable restricted and multiverse repositories, then update and install ubuntu-restricted-extras package

Hope if helps
