So you just did your ubuntu install and you setup your favourite media player be it amarok for you kubuntu people or xmms or bmpx (bad ass player) and your there twiddling your thumbs wondering whats wrong i know whats wrong.. theres no music to play jackass… this is wha tyou do

pull up a terminal:

sudo apt-get install sun-java5-bin

when thats done you download the forstwire deb package for ubuntu from frostire.com

back to the terminal:

sudo dpkg -i  Froswire-x-x-x-ix86.deb

then after that you wanna configure your java by doing this in the terminal:

sudo update-alternatives –config java

select the 3rd option and in case they decide to move something around your looking for the number that corresponds with this :  /usr/lib/j2sdk1.5-sun/bin/java

aftere that you should be able to start frostwire and download at your hearts content.
