Bug#624148: asterisk-config: System goes down due to unattended-upgrades

[John Goerzen]

Package: asterisk-config
Version: 1:1.6.2.9-2+squeeze2
Severity: grave
Justification: renders package unusable

I use unattended-upgrades to provide security updates.  This normally works fine,
and although I expect that an upgrade might take down Asterisk for a few minutes,
this took the system down and did not bring it back up.  I'm going to guess it was
related to this:

Setting up asterisk-config (1:1.6.2.9-2+squeeze2) ...

Configuration file `/etc/asterisk/sip.conf'
 ==> Modified (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** sip.conf (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing asterisk-config (--configure):
 EOF on stdin at conffile prompt

I can't imagine why the shipped conffile would have had to change for a security update.

And, indeed:

dpkg: dependency problems prevent configuration of asterisk:
 asterisk depends on asterisk-config (= 1:1.6.2.9-2+squeeze2) | asterisk-config-custom; however:
  Package asterisk-config is not configured yet.
  Package asterisk-config-custom is not installed.
dpkg: error processing asterisk (--configure):
