I've been peeking into the ubuntu respository and I see four folders, multiverse, universe, restricted and main. What do they represent?

Best Answer
From the Ubuntu documentation:
For example:
The Ubuntu Desktop team manages the
gnome-terminal
package, it is officially supported and in themain
repository.bcmwl-kernel-source
(the Broadcom wireless driver) is inrestricted
, since it is a supported, but proprietary, driver.Community written software that is not officially supported (for example, the game
supertuxkart
) is in theuniverse
repository.Packages like
ubuntu-restricted-extras
(which contains proprietary codecs that allow you to play media files, including flash player) are in themultiverse
repository because they are not free and their restrictive licenses prevent inclusion in the default package set.From Wikipedia:-
