Since 96% is in use, not 100%, you will still be able to install small
programs. Install ncdu (NCurses Disk Usage):

sudo apt-get install ncdu

then run it as root:

sudo ncdu -x /
(the -x option tells it to only look on the same filesystem)

I have given this advice several times on this list, and in all cases
people have thanked me. :)
