Error Summary

This is our production server. How do I safely resolve this?

If I run

sudo yum install kernel-headers

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

 * base: centos.excellmedia.net

 * extras: centos.excellmedia.net

 * updates: centos.excellmedia.net

Package kernel-headers-3.10.0-862.9.1.el7.x86_64 already installed and latest version

Nothing to do

sudo yum install kernel-devel

  • You can try this: yum install “kernel-headers-uname-r == $(uname -r)”. I believe it should work if there is a matching package in the repository. – Vinod Aug 9 '18 at 10:47
