Installing Ubuntu with no internet access

[Pierre Equoy]

Hi Gerhardus,

In your preseed file I see this:
d-i clock-setup/ntp-server string ntp.ubuntu.com

That means, at least at this stage, the installer will try to sync with the
NTP server at Ubuntu.com.

There might be other stages where by default the installer tries to reach
out the Web (e.g. it might check for new versions of packages), and that
may need to be disabled using some additional preseed info.

Sorry to be so vague, I'm not familiar with the internals of the Ubiquity
installer.

Another option might be to set up the timeout to be very short, as
explained in this Wiki article [1].

Hope this helps!
