[Bug 573633] Re: package mysqmail 0.4.9-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 10

[Martin Pitt]

Jean-Baptiste,

thanks for looking into this. I have some headache about the newly
introduced

+++ mysqmail-0.4.9/debian/mysqmail.postinst

+# Always delete the config file first.
+rm -f ${PATH_CONF_FILE}

A package should never remove a configuration file in /etc/ without
further checks. It looks like it would re-create it from debconf, but
that's the wrong way around: if the admin changes stuff in /etc/,
debconf should adapt. (debconf is a cache, /etc/ is the authoritative
configuration).

Bug description:
Binary package hint: mysqmail

Mysqmail package won't remove or re-install. Always get an error.

TEST CASE:
1. install mysqmail from a terminal:
  $ sudo apt-get install mysqmail

VERIFICATION SUCCEEDED:
1. If dtc-core is not installed the following message is displayed
The postinstallation script of MySQMail couldn't find /var/lib/dtc/saved_install_config
you will need to run dpkg-reconfigure mysqmail once DTC is installed in order to have
mysqmail working. I will exit silently but you MUST do the above.
MySQL debconf configuration missing: will silently exit now.
Please do dpkg-reconfigure mysqmail once DTC is installed in
order to have mysqmail working.

2. If dtc-core is installed the configuration of the package goes on
