That appears to show some packages that are not installed, for example I see
153704    linux-image-extra-3.18.0-13-generic 3.18.0-13.14
153841    linux-image-extra-3.16.0-23-generic 3.16.0-23.31
153841    linux-image-extra-3.16.0-24-generic 3.16.0-24.32
153853    linux-image-extra-3.16.0-25-generic 3.16.0-25.33
but according to synaptic those are not installed.
