Where is the MinimalCd / mini.iso for Groovy Gorilla?

The mini.iso for 20.10 (and newer versions) was not produced.
We have already asked Canonical to continue providing such images. But no luck.

So personally I'm happy with the following solution:

1. Download mini.iso for 20.04 LTS (Focal Fossa) from

   http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/current/legacy-images/netboot/mini.iso

   ^{Or create your own mini.iso with HWE 5.13 kernel using this answer and install from it, then go to step 3 below.}

2. Install the minimal system from mini.iso for 20.04 LTS (Focal Fossa)

3. Upgrade just installed minimal system from 20.04 LTS to latest non-LTS release

   sudo sed -i "s/Prompt=lts/Prompt=normal/" /etc/update-manager/release-upgrades
   sudo do-release-upgrade
   

4. Use minimal Ubuntu non-LTS system as a starting point.

I will use this solution until Canonical developers change their mind about this problem.
Existence of netboot mini.iso is essential thing.
It is a way to have highly customized system (yes, without Snaps) to start from scratch, to use apt with --no-install-recommends and --no-install-suggests on minimal system to keep it really minimal.
It is like stage3 for Gentoo. Even Ubuntu 4.10 (Warty Warthog) has this installation media in place.
It should be noted that Debian still have netinst images for stable and even testing versions.
So I hope that the next LTS - 22.04 LTS will have traditional mini.iso in place.
