I've been trying to get vagrant to work with virtualbox for hours now and I've been trying different combinations of versions of both. I finally got the whole thing working but during the painful process I wondered the following (I am a linux noob btw so please excuse me if these questions sound really dumb and vague)
When I uninstall virtualbox (or any application for that matter) through Ubuntu software centre does it leave any extra garbage (kind of like windows and registry) that could possibly cause future problems (e.g. during upgrades, reinstallations)? Or are they (or at least virtualbox) completely encapsulated (kind of like .app files on OS X) that I probably won't ever need to worry about it after removal?
Is there any relatively easy and safe remove all these garbage leftovers (if any) to ensure I don't have version problems later on?
Thanks in advance
