[Pkg-nagios-devel] Bug#918219: nagios3-cgi: postinst script fails if supplied apache config has been deleted previously

[Alex Sheppard]

Package: nagios3-cgi
Version: 3.5.1.dfsg-2+deb8u1
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

  Simply updating the system


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

  apt-get update && apt-get upgrade


   * What was the outcome of this action?

This packages  and the depending nagios3 package were left unconfigured / incompletely installed


   * What outcome did you expect instead?

The packages to install cleanly




   * More Detail

We use our own custom apache vhost to server nagios and so deleted the packaged /etc/nagios3/apache2.conf

The postinst script calls  'ucf --debconf-ok /usr/share/nagios3-cgi/apache2.conf /etc/nagios3/apache2.conf' which responds with
"Not replacing deleted config file /etc/nagios3/apache2.conf"

Then a few lines later 'apache2_invoke enconf nagios3' fails and results in an exit code of '1' from the postinst script.

I think this ought to be a warning, rather than an error.
