John Reyes
  • Updated

Symptoms

 

The KernelCare cronjob fails with the following where $KERNEL_RELEASE is the running kernel version.

 

Unknown Kernel (CentOS Linux $KERNEL_RELEASE)

 

Running the command listed below in SSH or WHM >> Terminal as root also results in the same message:

 

# kcarectl --check
Unknown kernel (CentOS Linux $KERNEL_RELEASE), no patches available

 

 

Description 

 

KernelCare will return "Unknown Kernel" when the server's kernel is not compatible with KernelCare. This typically occurs when updating to the latest kernel before KernelCare has released a patch.

 

Workaround

 

Confirm KernelCare has released a patch for the kernel. Please see: Is my kernel patched by KernelCare?
