I need to automate
apt-get installation of
kde-plasma-desktop which winds up installing both
lightdm Display Managers.
debconf-set-selections prior to installation to set the following values:
# Default display manager: # Choices: kdm, lightdm kdm shared/default-x-display-manager select lightdm lightdm shared/default-x-display-manager select lightdm
However, when I run
apt-get I still get prompted during configuration to select the default Display Manager. I've studied the configuration scripts for both packages, but still not getting it. They call
db_input high shared/default-x-display-manager unconditionally, yet it only asks the question if there was a prior value for the question.
How can I suppress this interaction so it can be run unattended?
