Install the appropriate kernel update from http://server.domain11.example.com/pub/updates. The following criteria must also be met: The updated kernel is the default kernel when the system is rebooted The original kernel remains available and bootable on the system the way i will do this: cd / then; wget http://server.domain11.example.com/pub/updates, ls -al if new kernel is there I will copy it somewhere and check current kernelswith the command #grubby --info=ALL ----this is to see all kernel then #grubby --default-kernel to see the default if its different from the new one to set new kernel use #grubby --set-default=/kernel/path then check with #grubby --default-kernel or STFN2019's solution dnf config-manager --add-repo http://server.domain11.example.com/pub/updates then; run #dnf update

yum config-manager --add-repo {given_url} yum update kernel

The solution to the questions seems very confusing. Best way is to update the repos and install the new kernel which becomes your default kernel anyway, no need for any further changes. Simply follow an e.g. link here: https://computingforgeeks.com/how-to-install-latest-kernel-on-centos-linux/

Question: You should be able to use wget to obtain the correct packages here, yes? Is the only reason they didn't because they don't have the full path/name of the file to correctly use the command?
