How to skip Server Snaps step on custom ISO installer

km flag

I'm building a custom 20.04 Server ISO and I would like to skip server snaps selection step during interactive installation. My understanding is it would be possible to do using preseed or autoinstall but I couldn't find in the docs how to do it.

I would suggest to also ask it in this topic: https://discourse.ubuntu.com/t/automated-server-installs/16612 the creator of autoinstall is in there ;-) (and since he had to redo preseed he also knows tons of stuff about that)

I found a way to solve that using autoinstall, using interactive-sections as follow:

autoinstall:
  version: 1
  interactive-sections:
    - locale
    - identity
    - keyboard
    - network
    - proxy
    - storage
    - apt
    - ssh

I was looking for a way to tell it that snaps would be the only non-interactive sections, but according to documentation it's not possible.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
