Kein GUI unter Ubuntu 15.10 installierbar

Nachdem die Desktops von KDE, LXDE, openbox und Plasma unbrauchbar schwarz wurden habe ich erstmal mit einem neuen User getestet und feststellen müssen das das Problem unabhängig vom User ist.
Also hab ich deinstalliert mit purge:

sddm sddm-theme-maui
kdm kdm-theme-bespin
kde-baseapps kdebase-bin kded5
plasma-framework plasma-desktop plasma-workspace

Danach machte ich reboot und versuchte neu zu installieren, aber das funktioniert nicht:

> aptitude install kdm
No candidate version found for kdm

Ebenso mit dem KDM-Nachfolger SSDM:

> Couldn't find any package whose name or description matched "SSDM"

Wie bekomme ich wieder eine GUI?

Hier die sources.list:
