Error message in testing upgrade

["Lonnie Sutton" <lsutton2@qwest.net>]

Good evening all,

I have just updated/upgraded my testing system this evening, and all
went OK except for one error message and I am unsure how to resolve the
problem that dpkg has encountered. The message is:

Preconfiguring packages ...
(Reading database ... 50115 files and directories currently installed.)
Preparing to replace xfree86-common 4.2.1-6 (using
.../xfree86-common_4.2.1-11_all.deb) ...

  Errors were encountered while processing:

   E: Sub-process /usr/bin/dpkg returned an error code (1)
   Ack!  Something bad happened while installing packages.  Trying to
   recover:
   Press return to continue.


Would someone be so kind as to point me to some reading so that I can
learn to interpret these messages and resolve the problem, or tell me
how to resolve the problem.

Everything seems to be working OK after the upgrade, but when I go into
aptitude, it still reports the "xfree96-common" package as upgradable.

Thanks in advance for your help.
