This will not be helpful, but it might be comforting and it might make you chuckle. I'm running my Koha instances on Ubuntu, and I haven't been able to install any Elasticsearch past 6.x, or on anything beyond Koha 22.11. I've gotten the "no nodes" error many times, also error messages about shards. Two instances have a status of green, one is still yellow. It works, which is the important thing.
My experience is that sometimes Elasticsearch installs successfully, sometimes it doesn't. When I tried to install Elasticsearch during a live demo at last month's koha-US conference (https://www.youtube.com/watch?v=sks5Jfb9drQ), it didn't go well at all, despite the fact that I had done a dress rehearsal the week before using THE EXACT SAME IMAGE AND COMMANDS. I didn't make a complete idiot of myself--my pants didn't fall down--but it wasn't one of my better presentations. When I got home I tried it again and it worked perfectly. I actually have a video of it in the works--I just need to add the narration. I should add that I'm unsupported, and although I have made and broken more instances of Koha than most of you, I'm definitely not an expert in fitting all the parts together.
