Better to use dpkg-divert to protect your modified nautilus.desktop than trying to use permissions. Here's the formula:
$ sudo dpkg-divert --add --rename --divert \ /usr/share/applications/nautilus.desktop.real \ /usr/share/applications/nautilus.desktop $ cp /usr/share/applications/nautilus.desktop.real \ /usr/share/applications/nautilus.desktop $ echo "AutostartCondition=GNOME /apps/nautilus/preferences/show_desktop" \ >> /usr/share/applications/nautilus.desktop This will cause upgrades of nautilus to write to nautilus.desktop.real rather than overwriting your modified version.
