cups-pdf fails during upgrade (was: package update-manager 1:0.78 failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:Sub-process /tmp/tmpM_pNBz/backports/usr/bin/dpkg returned an error code (1))

Traceback (most recent call last):

IOError: [Errno 9] Bad file descriptor

It stopped after the line that says "IOError:". It told me earlier that it couldn't install cups-pdf. I can't go back up that high in the terminal window, but it said something along the lines of "lpstat: Attempting to contact server..." and then "lpadmin: Could not contact server.", or something along those lines. I don't know if it's related to having remote printers set up? Especially my default printer being a remote printer? Let me know if you need more information, I'll help in any way I can.
