I am new to Linux, BUT, not for long it seems. Whenever I try to download and install software that is specific for Kubuntu on a Mac Mini PowerPC , I go through to terminal to sudo it and guess what, it does not work. The multimedia players that I have also do not work as they are apparently missing parts. If this is the future of Kubuntu, then I am sorry but I will have to revert back to Mac OSX. At least I could download things such as Limewire and the like. Any ideas as to what I am doing wro...
