Bypass “Package Configuration” Screen

Question

I'm trying to setup my Ubuntu image via a script over on AWS and I can't get rabbitmq-server to install. It throws a Package Configuration screen that simply has one option (hit OK).

How can I bypass this? It causes my script to hang

Answer 1

It sounds like your install script is being stopped by a debconf dialog. You can suppress the debconf dialog by setting the environment variable DEBIAN_FRONTEND to noninteractive. For example:

DEBIAN_FRONTEND=noninteractive  apt-get install rabbitmq-server

In general, if you want to script package installations using non-default configuration settings, you will need to preseed the debconf database with the desired settings. I recommend you read the debconf man page, and pay particularly close attention to the section titled "Unattended Package Installation".

Answer 2

You might be able to use python fabric to do what you need.

In Stackoverflow, someone asked a question similar to yours so you can refer to that.
