on apt Update conflict nginx files

[kangarooo]

Ubuntu 16.04 64bit
did sudo apt update sudo apt upgrade
later one up updates asks this and i pressed to check differences and looks like its some easy eangine lines in both but witch one is real? How this came if if did before ee update and it told all is ok - i have latest version. So if this one isnt easy engines, then this one might overwrite something from ee and ee will not work some cache app part maybe?

Configuration file '/etc/nginx/nginx.conf'
==> Modified (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.
*** nginx.conf (Y/I/N/O/D/Z) [default=N] ?
