I have a full ubuntu mirror located on the server
In my preseed.cfg file, I have the following d-i config for selecting my country mirror:
d-i mirror/country string manual d-i mirror/http/hostname string leelah.home.ianwilson.org d-i mirror/http/directory string /ubuntu d-i mirror/http/mirror select leelah.home.ianwilson.org
I can tail my access_log file to see that my preseed file is being retrieved from the installer, but nothing else. When I look at my network traffic, I am seeing that traffic is going to archive.ubuntu.com, and not my local mirror.
If I select "Manual mirror" and specify my mirror server during the guided install, it does use the local mirror, however, any attempt at trying to do this via preseed completely fails.
What should I be placing in my preseed file in order to get the installer to default to my local mirror?
