    Hello,

    I have a version of cPanel&WHM 70.0.53. I have ran command yum -y update to update kernel after I received message New Security Advisor notifications with High importance (The system kernel is at version “3.10.0-862.6.3.el7.x86_64”, but an update is available: 3.10.0-862.9.1.el7.x86_64)

    And my kernel now is 3.10.0-862.9.1.el7.x86_64.

    But I received a message that :

    Unknown Kernel (Red Hat Enterprise Linux Server 3.10.0-862.9.1.el7.x86_64

    What shall I to do now?

    Best regards,
    Elizabeta

    Hi @Elizabeta

    You're getting that notification message because kernelcare free patch doesn't have support for the newest kernel version. They should be adding it later this week. Though I don't think it supports RHEL and we do have a case open for this currently CPANEL-21185.

    To remove the free patchset you would just need to run the following:

    Code:
    yum remove kernelcare

    Hello,

    Thank you Lauren for this explanation. I´ll wait for free patch. I suppose this patch will be installed automatically.

    Best regards,

    Hello,

    I have ran command
    kcarectl --set-patch-type free --update

    And
    [root@cptest kcare]# kcarectl --info
    kpatch-state: patch is applied
    kpatch-for: Linux version 3.10.0-862.9.1.el7.x86_64 (mockbuild@x86-017.build.eng.bos.redhat.com) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) ) #1 SMP Wed Jun 27 04:30:39 EDT 2018
    kpatch-build-time: Tue Jul 17 22:40:29 2018
    kpatch-description: 2-;3.10.0-862.9.1.el7

    I´m not sure that is free patch, is this patch trial version of KernelCare??

    Best regards,
    Elizabeta

    Hello,

    Just one info:

    I ´ve got this e-mail-:


    Requesting trial license for <IPRemoved>, please wait...

    HTTP Error 403: Forbidden, Retrying in 3 seconds...

    Requesting trial license for <IPRemoved>, please wait...

    HTTP Error 403: Forbidden, Retrying in 6 seconds...

    I would like to know is this free patch installed or trial from KernelCare?

    HI @Elizabeta


    For some reason it does seem like it was trying to install a trial license. Can you show me the output of the following:
    Code:
     kcarectl --license-info
    But again, based on the comments on their page this will only be useful for CentOS 6 or CentOS 7 https://www.cloudlinux.com/imunify360-imunifysensor-blog/entry/the-kernelcare-extra-patchset-with-symlink-protection-is-now-available
    It is not compatible with RHEL

    "Extra and Free patches are available only for CentOS 6 and 7, not for RHEL
    So trial patches of KernelCare were applied"

    You're running RHEL there's no point in continuing to attempt to troubleshoot the installation when the patch is not compatible with your OS.

    Hello,

    Thank you Lauren for this answer.

    Here is the results of command:
    [root@cptest kcare]# kcarectl --license-info
    You have a trial license for the IP 212.39.111.94 that will expire on 2018-08-02

    Ok, there is no sense to troubleshoot the installation when the patch is not compatible with RHEL.

    Best regards,
    Elizabeta

    Hi @Elizabeta

    It does definitely show you running a trial license for kernelcare. If you don't want kernelcare (the full product) you can uninstall it by following the instructions here: http://docs.kernelcare.com/

    Code:
    yum remove kernelcare
    There's no reason in allowing it to remain on the server if you don't want the full product since the free patchset won't work for you.

    Thanks!
