php5-fpm upgrade broken after deleting sample config

[Stanislaw Pitucha]

If the sample config is not available anymore, php5-fpm cannot be updated automatically and leaves the service down.

Every production deployment will want to remove /etc/php5/fpm/pool.d/www.conf and use its own configuration. But when an automatic security update comes in, this results in:

# apt-get install
....
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Setting up php5-fpm (5.5.3+dfsg-1ubuntu2.5) ...

Configuration file `/etc/php5/fpm/pool.d/www.conf'
 ==> Deleted (by you or by a script) since installation.
 ==> Package distributor has shipped an updated version.
...

This should never break when unattended security updates are running.

www.conf is a conffile. Deleting it should not replace it when the package is upgraded.

If updating manually, the following prompt should appear:

Configuration file `/etc/php5/fpm/pool.d/www.conf'
 ==> Deleted (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.
*** www.conf (Y/I/N/O/D/Z) [default=N] ?

Do you perhaps have the following option set up in apt somewhere?

Dpkg::Options {
   "--force-confmiss";
}

I'm using the default apt/dpkg config. (apart from turning on auto security updates) Also yes, this is exactly the message I get.

The problem is that the unattended upgrade also gets that question and stop with package not configured.

Could you please attach your /etc/apt/apt.conf.d/50unattended-upgrades file?

Filtering out unneeded stuff:

=====
$ grep -v -e '^$' -e '^//' /etc/apt/apt.conf.d/50unattended-upgrades
Unattended-Upgrade::Allowed-Origins {
 "${distro_id}:${distro_codename}-security";
};
Unattended-Upgrade::Package-Blacklist {
};

I did answer the questions asked. Reverting to "new" rather than "incomplete".
