Google can help with that Question is a very common issue. As the message said you need the sources of your kernel so install it by running ‘yum -y install kernel-devel’

Pay attention that you need the same kernel-devel version as your kernel . If its not in production use or you dont have any restriction on updating kernel I suggest you to run "yum install kernel kernel-devel "

Than you very much :smile:)

Why are you trying to install them on a system that can’t use them?
