This article covers method to fix cPanel Error Iproute Conflicts With Kernel. Basically, this error happens when we have an outdated kernel on the server.
Instead of deleting conflicting kernels, you can also add the iproute package to the excludes of yum in /etc/yum.conf file, then the iproute package won't be marked for the update.
It can be useful when you need to perform an update but can't reboot the server at the given moment.
It can be excluded manually using a preferred text editor or using the following command:
$ sed -i 's/exclude=/exclude=iproute /' /etc/yum.conf
The change can be reverted using this command:
$ sed -i 's/exclude=iproute /exclude=/' /etc/yum.conf
