سلام.
من با دستور زیر yum groupinstall 'GNOME Desktop Environment' 'X Window System' سعی میکنم GNOME رو روی VPS ام نصب کنم... ولی خطای زیر رو میگیره:
Warning: Group x11 does not have any packages.

گفتنیه که من قبلا یه بار نصبش کرده بودم ولی چون اجرا نمیشد پاکش کردم با دستور:
yum groupremove 'GNOME Desktop Environment'


اطلاعات دریافتی کامل بعد از دستور yum groupinstall 'GNOME Desktop Environment' 'X Window System
