Goal

Using the latest LTS server iso (alternate), which at the time of writing is ubuntu-18.04.1-server-amd64.iso, I want to be able to do an installation, using a preseed and a kickstart file hosted on a webserver, however I cannot use DHCP.

So I am looking for a way to manually set the IP address when booting up the installer.

Steps previously taken

I have tried using the ip kernel parameter. I've tried the various forms of it, leaving out some fields and other times leaving them empty – the options are detected during boot-up (see below screenshot), but they do not seem to come into affect. I've also both tried adding it before and after the two dashes.

I have tried this with the 16.04 server iso as well.

Note

It is not possible for me to use TFTF, PXE or anything like that. Also, I do not want to have to make custom installers, I want to be able to use the iso from the mirror.

Final remarks

If this is simply no longer possible, could someone please refer me to where this change was documented? I can not find any information indicating so.
