after installing security patches on ubuntu 18.04 the yml config file was revert to default like all was commented again
on the logs I see this see this:

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.
