Disk too full?

[Charles Blair <c-blair@illinois.edu>]

   I think I'm running out of space on my
laptop.  The last time I got an "updates
available" message, I got a further warning,
during the update, that I was low on space.
The update did seem to complete, though.

   However, when I tried to use the calculator
program dc afterwards, the computer just sat
there.

   Below is the output from the df command.
Thanks very much for any help!
