Hello, I am getting an error while updating the Centos 8 kernel. Can you help me.


Error:

The package you are trying to install is

a) not supplied by CentOS
b) is not signed by a GPG key that you have told yum to trust

You need to ask "kernelcare" for support

Is there a resource about this?

How can I do it?

Kernelcare is a commercial offering that supplies kernel updates without needing to reboot. It's not a part of CentOS, it's something you have to pay for. Since you pay for it, they will offer you support to fix their issue.
