Cloning an Ubuntu 18.04 physical server

Question

I am working on cloning an Ubuntu 18.04.2 physical server, I use clonezilla for cloning, however, when I apply that image to any other servers (and of course I change the hostname and static IPs), I find that the MAC addresses stay the same, which causes a mess in my network.

It seems the MAC addresses are hardcoded somewhere, do you have any idea where I can reset these MAC addresses to use the real ones of the other servers?

You could search for a given address to find which files contain it: https://askubuntu.com/questions/1005437/greping-all-files-for-a-string-takes-a-long-time — WinEunuuchs2Unix, Jul 03 '19 at 10:23

This has been resolved by deleting the /etc/machine-id file and rebooting or just using the systemd-machine-id-setup utility.
