@Dv27842 said in Unable to change IP for FOG Server installation on Ubuntu Server 18.04: I have tried to change the IP address to a static IP address that is currently on my sandbox, but it will not keep the changes Please give us more details. Where exactly did you try to change the IP? Within Ubuntu? Which file did you edit? What did it look like before? I can imagine you were editing the wrong file. Ubuntu 16.04 network config is different than Ubuntu 18.04, see here: https://www.ostechnix.com/how-to-configure-ip-address-in-ubuntu-18-04-lts/
