[Bug 1169044] Re: can't install/upgrade postfix non interactively through apt

[Robie Basak]

Thanks for going through this with me.

It seems that you have two problems:

1) You're asked to accept the changelogs before the upgrade proceeds.
2) You're prompted by debconf for postfix configuration options before the upgrade proceeds.

The first is due to your decision to install apt-listchanges, its local
configuration on your system, and possibly bug 788519. Try running "sudo
dpkg-reconfigure apt-listchanges" to see if it has any debconf options
to stop it prompting you, see the bug for a workaround, or just remove
the apt-listchanges package if you don't need it.

The second is the standard debconf prompt. See debconf documentation for
details on this. Based on the debconf settings on your system, it looks
like the question wasn't answered before and so it is asking it again.
This is expected behaviour. To suppress the prompt entirely, try setting
DEBIAN_FRONTEND=noninteractive.

For the first issue, please refer to bug 788519, or file a new bug
against apt-listchanges if you think you have a different issue with it.
The second issue is not a bug in the postfix package, so I'm marking
this bug as Invalid in postfix.
