apt-get install -y doesn't work with license agreements, how to automate that?

Solution 1:

There are some ways to do this:

Pre-answer with debconf by executing the following command before installing:

echo sun-java6-jdk shared/accepted-sun-dlj-v1-1 select true | \
    /usr/bin/debconf-set-selections

Use expect:

#!/usr/bin/expect -f
sudo apt-get -y install sun-java6-jre
expect "[y/n]"
sleep 1
send -- "yes\r"
