When performing an APT upgrade through KPackage, the followin appears in the dialog window:
Setting up foomatic-filters (3.0.0-20031207-1) ...
Configuration file `/etc/foomatic/filter.conf'
==> File on system created by you or by a script.
==> File also in package provided by package maintainer.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a new shell to examine the situation
The default action is to keep your current version.
*** filter.conf (Y/I/N/O/D/Z) [default=N] ?
The problem is, pressing the Enter key just moves it to the next line instead of returning my response to the prompt, and the only thing I can do to get past it is to press Ctrl-C, which produces the following:
dpkg: error processing foomatic-filters (--configure):

The only edit I've done to my /etc/apt/sources.list file is to add the line for developer.linuxtag.net/knoppix.

Has anyone else encountered this problem?
