Just a quick question. You know how in Windows, because of poorly-written programs, sometimes installing and uninstalling a program will leave records in the Windows Registry or AppData folder of a user? Will that happen in Ubuntu if I install and uninstall a program too?
As far as I am aware, Ubuntu doesn't really have a registry (all data is stored in files), and using the purge
option in Aptitude is supposed to "completely" remove all files related to a program (does it always work?).
