KernelCare Update

Peter Smith
Hi, I keep receiving emails when the kernelcare update cron job runs. The cron job is trying to run: - "/usr/bin/kcarectl -- auto-update" I'm getting the error 'substring not found' This is the free version of kernelcare but I've never come across this error before. Any help would be greatly appreciated. Thanks - Peter

    Hello @Peter Smith Can you run the following on your server and let me know the output? kcarectl --patch-info
    Can you also let me know the kernel version you're currently running?

    Hi @Peter Smith That's not exactly what I had asked to run but I think it still answers my question. If you're only trying to run the kernelcare symlink protection patch this isn't compatible with the kernel you have installed. KernelCare's symlink protection (free ) patch is ONLY compatible with stock the stock CentOS kernel, in your case you're running a CentOS plus kernel. Thanks!

    Should it be removed? How would it be removed?
