12.04 - I wish to find how the package was installed

i going upgrade package in ubuntu , had doubt how installed in server. how can check if installed source i.e. using make command or via apt-get/yum?

i have searched lot of forums confused. can check via rpm qa command in centos?

sorry if question simple not getting answer.

thanks

if package installed compiling manually apt-get/dpkg not have track of package, , hence it's contents.

you can check if dpkg has track of installed package:

dpkg --get-selections | grep 'package_name_or_pattern'

dpkg -l 'package_name_or_pattern'
