#tag Debian,Java,gotchas,debconf
Installing the Sun Java packages on Debian or Ubuntu require to you
accept Sun’s license before you can install them. This means that it’s
not easy to install non-interactively, for example when using
pbuilder. Fortunately the license uses
debconf to check to see if you have already accepted the license. This
means you can use debconf to accept the license before you install the
packages. Create a file containing the following lines:
sun-java5-jdk shared/accepted-sun-dlj-v1-1 select true sun-java5-jre shared/accepted-sun-dlj-v1-1 select true sun-java6-jdk shared/accepted-sun-dlj-v1-1 select true sun-java6-jre shared/accepted-sun-dlj-v1-1 select true
Then run /usr/bin/debconf-set-selections <file> and
when you install the java packages, you should find it doesn’t prompt
for the license any more.

debconf-set-selections also accepts input from stdin so you could also do:
echo sun-java5-jdk shared/accepted-sun-dlj-v1-1 select true | /usr/bin/debconf-set-selections
echo sun-java5-jre shared/accepted-sun-dlj-v1-1 select true | /usr/bin/debconf-set-selections
echo sun-java6-jdk shared/accepted-sun-dlj-v1-1 select true | /usr/bin/debconf-set-selections
echo sun-java6-jre shared/accepted-sun-dlj-v1-1 select true | /usr/bin/debconf-set-selections
Useful if you are installing java in a bash script and don’t want to create a seperate file.

Hi Jeff,
Thank you SO very much for this information. I’m using an Emulab-like environment in which I install nodes with Java all the time, finally I found your great post about this!
Thanks!

By the way, you don’t happen to know a way of installing xorg so that it doesn’t prompt for the screen resolutions? That’s the only thing left for full automation.
So when I
apt-get -y install xorg
the installer asks my which screen resolutions I want to use. The defaults are fine for me, but how do I disable this (for me) redundant prompt?
Thanks even more! 🙂

Just to make it a bit easier on my eyes in script 🙂
cat << EOF | /usr/bin/debconf-set-selections
sun-java5-jdk shared/accepted-sun-dlj-v1-1 select true
sun-java5-jre shared/accepted-sun-dlj-v1-1 select true
sun-java6-jdk shared/accepted-sun-dlj-v1-1 select true
sun-java6-jre shared/accepted-sun-dlj-v1-1 select true
