When you do updates it will cache the package files that it has 
downloaded.  If you run the command:

sudo apt-get clean

...from a terminal it will clear out the archive packages and hopefully 
free up some space :-)

You'll probably not notice it so much when you install to a hard drive 
as generally you'll have much more free space (unless you happen to be 
running on old kit with a smaller hard drive).
