Some times things go wrong and you want to restore default configuration files.
This quick tip is devoted to debian based distributions
One may think that the apt-get flag - -reinstall will do the trick, however that's not enough. You'll need to provide some not-so-obvious arguments:
apt-get -o Dpkg::Options::="--force-confmiss" install --reinstall package-name
With that command the missing configuration files and missing directories will be re-deployed.
If you need to, you may want to remove the messed configuration files that you want to restore before issuing the command.
