Install Ubuntu server 22.04 without internet

From this link, I've seen that there are two versions of installers for Ubuntu Server 18.04, which one uses the internet, but the other doesn't.
On installing Ubuntu Server 22.04 I get error on the following log:

configuring apt  curtin command in-target

Why there's no standard installer for the 22.04 version on this link?
How should one now install Ubuntu Server 22.04 while not having connection to the internet?

Here's the installer log.
