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.
*** cloud.cfg (Y/I/N/O/D/Z) [default=N] ?
그냥 Y 하면 되나요?
Selecting the first option,
Y or I : install the package maintainer's version, will not change your currently installed Ubuntu release. Instead it will make everything compatible with your currently installed Ubuntu release (Ubuntu 16.04). If necessary it will undo changes that you have made in your system that could prevent you from being able to update packages normally. The firstYoption is the safest option to choose when presented with thePackage distributor has shipped an updated versionmenu because it is the option the allows you to update your system normally and returns your system to a condition where there is nothing that interferes with default package management. This will also make it easier to fix the underlying broken packages problem that interferes with updating the installed packages and probably generated this package management message to begin with.구글링 해보니깐 첫 번째

그냥 Y 치고 깔고 나니 나중에 이글은 왜 뜨는지?
