Why dpkg asks "Override local changes to /etc/pam.d/common-*?" when libpam-runtime/override is set to false?

  • 772

In my system, libpam-runtime/override is set to false (which I can see using debconf-get-selections).

Why when upgrading the system, specifically libpam-systemd, dpkg still pops up the window "Override local changes to /etc/pam.d/common-*?"? Should I preseed some other value? I can't find any.

The machine is an Ubuntu 14.04 server.

  1. With Debian Jessie, explicitly setting the libpam-runtime/override value as follows avoided the interactive question during cloud-init:

    runcmd:
  - 'echo "libpam-runtime libpam-runtime/override boolean false" | debconf-set-selections'
  - 'apt-get update'
  - 'apt-get -y install sssd-ldap'
  - 'systemctl enable sssd'
  - 'systemctl restart sssd'

  2. Sounds like https://bugs.launchpad.net/ubuntu/+source/pam/+bug/682662:

    It is by design of debconf that settings on the system take precedence over any values set in the debconf database.
