Already tried dpkg-reconfigure cupsys as root. No go.

I think there may be
a syntax error in the cupsys.postinst script.

 Is there a way to
run the script "properly" i.e., tell dpkg to run it in a verbose
manner?

 If you noticed, (I put the output of set -x in it)
when I ran the script directly it does give a syntax error message that
may or may not be due to the fact that I ran it directly which may well
be "incorrect".

Here is the output of dpkg-reconfigure after (by putting in set -x in
the postinst script of cupsys):

# dpkg-reconfigure -plow cupsys
