Comment 10 for bug 659754

Well, consider the case where somebody installs ubuntu-netbook-efl-default-settings on a system that has nothing to do with these preinstalled images. It clearly shouldn't edit sources.list in this situation.

The difference between le-nl and le is that the former happens when you install the package and it wasn't already installed, while the latter happens when upgrading the package from a previous version.

Is the miscommunication here that when Steve says "install" he means "dpkg -i ubuntu-netbook-efl-default-settings.deb", but when you (Oliver) say "install" you mean "install entire system that contains ubuntu-netbook-efl-default-settings"?
