So according to those logs, lightdm recommends unity-greeter.

It looks like that can also be resolved using lightdm-greeter.

mythbuntu-lightdm-theme doesn't provide lightdm-greeter, but it's dependency lightdm-gtk-greeter does.


I'm unsure why update manager didn't see lightdm-gtk-greeter as resolving the lightdm-greeter dependency for lightdm.
