I'd like to know in common how to use the results of debconf-show with debconf set selections to precvonfigure deb packages with the command line or within a shell script
If I use
sudo debconf-get-selections | grep java7 > result;cat result
I get the following
oracle-java7-installer shared/present-oracle-license-v1-1 note oracle-java7-installer oracle-java7-installer/local string oracle-java7-installer shared/accepted-oracle-license-v1-1 boolean true oracle-java7-installer shared/error-oracle-license-v1-1 error oracle-java7-installer oracle-java7-installer/not_exist error
How would the right debconf set selections line look like to configure the two dialoges that appear trough the installation?
In general how is the right syntax of debconf set selections I assume there are not only booleans like true or false and yes or no
I guess there is much more an other example will be how to select the default desktop manager if lightdm and gdm installed by a bash script.
Is there a general proofed approach to determine and the right values for a debconf package and write a proper bash script that installs something like the webupt8 java package and preselect the values that the user normally would be asked for?
