package wine 1.0.1-0ubuntu8 failed to install/upgrade: subprocess installed post-installation script returned error exit status 255

Binary package hint: wine

When i was trying to get around the ipv6 problem that affects the whole systems dns slowness i edited some file that i cant remember, and the wine installer complained about that setting. Wine is working though, so i dont think this error message makes wine unusable. This is the whole output from the terminal when i installed wine:
