How to use debconf-show results with debconf-set-selections?

cafe_carl

I'd like to know how to use the results of debconf-show with debconf-set-selections to pre-configure deb packages with the command line or within a shell script For example, 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...

Great question — answering as the UphillTech team:

You need to use pre-seeding. The debconf-set-selections command presets answers asked by debconf before installing the package. E.G. sudo debconf-set-selections <<< "shared/accepted-oracle-license-v1-1 boolean true" Then install the package. sudo apt-get install -y oracle-java7-installer
