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


Error:

Public key for kernelcare-2.34-1.el8.x86_64.rpm is not installed
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'yum clean packages'.

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
CentOS 6 will die in November 2020 - migrate sooner rather than later!

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.
