Most of my day today was spent installing Ubuntu on older computers. Microsoft's software had crashed and they needed their computer for checking their email, banking etc. After updating the restricted hardware drivers I fix the most common issue people have with Ubuntu-- "Not being able to play protected formates." To fix this the terminal command is.
sudo apt-get install ubuntu-restricted-extras
Enter your password and you are ready to use your computer. I like to copy more then one item so I also install parcellite.
