Thanks for helping, but none of your answers solved the problem, I can install/remove xmule but amule can't be removed nor upgraded.
Another thing I don't have any ed2k file at all when I remove xmule(I probably removed ed2k.amule, I'm not sure of it). I tried to install xmule, copy ed2k as ed2k.xmule and ed2k.amule, but it didn't help, he keeps telling me about the diversion. Is there a clean way to remove every file of the packages? It's really bothering me because it blocks the upgrading of my system (around 60 packages are pending to upgrade).
