How to install kairos on incus?

[onlookor]

I failed at the first step: import image.
I downloaded a kairos ISO image from github release, tried the command:
incus image import kairos-alpine-3.19-core-amd64-generic-v3.2.1.iso
And get an error: Unsupported compression.
Some guide told me to use the squashfs image, but incus image import reported an error:
Metadata tarball is missing metadata.yaml
So, I have to make up a metadata.yaml, but it doesn't work anyway.

In the past, I had some success to run abcdic on LXD (see polymorphic OCI OS images with Kairos #1875 context), I don't know if it's still the case with more recent version or with incus. I published some howto details (see end of that page : https://framagit.org/j-landru/abcd/-/blob/main/README.sav20240530.md?ref_type=heads#lxd- ), maybe some tips are still useful.
