I am new user and i installed Ubuntu 12.04 with dual booting. As I played a song its not working asking a MPEG1 to install for the song. Is there any alternative to play the song without installation. I searched the sites and i found to install
sudo apt-get install Ubuntu-restricted-extras
I have connected INTERNET from android mobile through tethering. I can access internet but it is very slow in downloading. I am trying from software center but its taking lot of time to install. Please help me to download the package via terminal and to download faster.
