Bug#818970: task-kde-desktop: package cannot be installed because of unmet dependencies

[Víctor Cuadrado Juan <me@viccuad.me>]

Package: task-kde-desktop
Severity: normal

Running Testing and trying to install KDE by tasksel gets
me unmet dependencies:

$ sudo tasksel -t  #select KDE, use the apt-get options directly:

$ LANG=C sudo apt-get -q -y -o APT::Install-Recommends=true -o
APT::Get::AutomaticRemove=true -o APT::Acquire::Retries=3 install task-kde-
desktop
