package installs unnecessary dependencies (review dependencies)

[Rafael Belmonte]

Installation of lightdm-kde-greeter installs many unnecessary dependencies, it installs around 98 packages, you can see the list of the installed dependencies in the screenshots I am attaching.
The problem is that unity-greeter and many other Gnome stuff is also installed.
Please review ligthdm depencendies.

Here are the direct depends of both. I don't see anything in the lightdm-kde-greeter depends that would pull in extra stuff.

[Scott Kitterman (kitterman)]

Oops. The lists didn't make it.

BTW, I tried to replicate your list on a clean system and didn't get nearly so many packages, so I'm not sure exactly what's up.

[Rafael Belmonte (eaglescreen)]

Current is:
Recommends:
    unity-greeter
        (Unity Greeter)
    or lightdm-greeter
        (virtual package provided by lightdm-gtk-greeter, lightdm-kde-greeter, lightdm-webkit-greeter, unity-greeter)

But since lightdm-greeter is also provided by unity-greeter, shouldn't be it as the following?
Recommends:
    lightdm-greeter
        (virtual package provided by lightdm-gtk-greeter, lightdm-kde-greeter, lightdm-webkit-greeter, unity-greeter)

Shouldn't you rename unity-greeter to lightdm-unity-greeter for concordance?

[Rafael Belmonte (eaglescreen)]

I can reproduce this issue of installing unnecessary depencencies when installing lightdm-kde-greeter from Moun Package Manager, but not when installing via apt-get in terminal.
