debconf

问题 I am setting up a bash script to automate the building of a LAMP environment. I am using debconf-set-selections to set options before installing mysql, phpmyadmin, etc ... It works mainly great.

问题 I have a problem with postinst script, I have to ask root password for MySQL to create some user for my application. I know, it's bad practice to use db_input in postinst however I really need it. Why this postinst doesn't work when I install my app form repository but works properly when I install it as .deb package? postinst: #!/bin/bash -e . /usr/share/debconf/confmodule db_input high my_app/mysql_root_password || true db_go error: dpkg: error processing my-app (--configure): subprocess

问题 I'm writing a Linux Shell Script to automate a few things I'm doing on Ubuntu 11.04. Basically, I'm writing a shell script to install NGINX, MySQL, and PHP, and then configure everything.
