I need to install
Java 1.7 on several machines and hence I want to do it using a script. The problem is the installation asks for certain options (to be specific 'Y', then 'OK' and finally 'Yes'). I came across this question:
Automate the installation of postfix on Ubuntu
I am pretty sure the process is on the same lines. But I don't know how did the OP know about the variable names (?) like
postfix postfix/mailname etc.
If someone can provide a more direct answer, it will be most appreciated.
I tried setting
sudo dpkg-reconfigure debconf to
non-interactive and selecting alert level as
critial. Then I tried to execute
sudo apt-get install oracle-java7-installer and got this error:
