Is there a way to check Ubuntu installation health?

view story

http://askubuntu.com – I'm a person who wants to be sure before continue working on his system. Because of that, I would like to know if my Ubuntu installation is in a good condition or not. Some of the things I would like to know: If there is a missing necessary package or not. All packages are healthy. There is no missing file in system. There is no broken package and etc... Long story short is there a way I can check if my installation is healthy, in a good condition or not. If that's important, I'm using 14.04 at the moment. Thanks. (HowTos)
