Pre-seeding debconf doesn't impact install of libdvd-pkg

  • 772

I'm raising this here as I'm not sure if this is a bug or if I'm just going crazy. But when I'm installing a new Ubuntu Desktop I like to use chunks of copy&paste-able lines to get useful stuff installed really quick... e.g...

echo ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula boolean true | sudo debconf-set-selections
sudo apt-get -y install ttf-mscorefonts-installer

Which works fine.

But when it comes to libdvd-pkg, I just can't get it to shut up (I don't want to use 'DEBIAN_FRONTEND=noninteractive'). Here is what I've tried...

echo libdvd-pkg libdvd-pkg/first-install note | sudo debconf-set-selections
echo libdvd-pkg libdvd-pkg/post-invoke_hook-install boolean true | sudo debconf-set-selections
sudo apt-get -y install libdvd-pkg

You always get this screen...

I've seen this happen on 12+ machines now, so it's not just a one off.

This is on Ubuntu 16.04 by the way.

Any ideas what I might be doing wrong to try and silence this?

I've inspected the DEBIAN/templates file within the .deb package and can't find anything unusual.

debconf

  1. Install manually the first time, then use debconf-get-selections | grep "^libdvd-pkg" to see what debian confirm uses. After that, put the result in a script and execute debconf-set-selections before installing the package.

    1) Run deb-conf-get-selections on a installed machine:

    #$ debconf-get-selections | grep "^libdvd-pkg"
libdvd-pkg  libdvd-pkg/build    boolean true
libdvd-pkg  libdvd-pkg/upgrade  note
libdvd-pkg  libdvd-pkg/post-invoke_hook-remove  boolean false
libdvd-pkg  libdvd-pkg/post-invoke_hook-install boolean true
libdvd-pkg  libdvd-pkg/first-install    note

    2) Put these lines in a installer script, before installing:

    #!/bin/bash

echo "Installing libdvd-pkg ... "

cat <<EndOfConfig | sudo debconf-set-selections
libdvd-pkg  libdvd-pkg/build    boolean true
libdvd-pkg  libdvd-pkg/upgrade  note
libdvd-pkg  libdvd-pkg/post-invoke_hook-remove  boolean false
libdvd-pkg  libdvd-pkg/post-invoke_hook-install boolean true
libdvd-pkg  libdvd-pkg/first-install    note
EndOfConfig

sudo apt-get install libdvd-pkg

    Done!

    You can do this in all packages who has dialogs and user interaction.
