Installing things always gives me following error

[danielgrosvenor]

Hi guys. I'm very new to Linux so hopefully this problem will have an obvious solution I'm just missing.

Every time I attempt to install anything, in any way, I'm given the following error message:

E: lib32nss-mdns: subprocess installed post-installation script returned error exit status 2
E: wine1.2: dependency problems - leaving unconfigured

I went into Synaptics Package Manager and told it to uninstall WINE in case that was what was causing the problems. It sort of half-uninstalled-it then gave me that exact same error message.

I have two threads currently open on the forums - adjusting laptop brightness (http://ubuntuforums.org/showthread.php?t=1500505) and flashing BIOS (http://ubuntuforums.org/showthread.php?t=1501007) - and both problems hit a brick wall because of this same error message.

As I'm new to Linux I have absolutely no idea how to proceed, so would greatly appreciate any advice you experts are able to offer me. :)

Have done so. Here is the result (hopefully it'll make more sense to you than it does to me!)
