Hello John, very kind of you for your reply. However, I did tried groupinstall and it shows error saying that there is none group list of that name. Even after yum grouplist and I see it there. It keeps failing. It only offer a solution: yum group mark install ... which is not the actual command for it to install. What may it be?
