I found that this issue happens when you install apps/games from extras-devel. To be able to install more applications you'd have to remove some of the existing applications from extras-devel. What I would like to know..is there some kind of work around? And does this problem occur by installing a certain amount of apps from extras-devel or by their size. Eg: the limit is 3 apps of 200 mb each (600mb) or 15 apps no matter what their size is?
