Same here, no fix so far?

Hi there, can you try setting the user to rocky, cloud-user, or stack instead? Unfortunately the README is a fair way out of date and support for CentOS 8 was dropped a while ago. The drop-in replacement is Rocky 9, and Ubuntu 22.04 also work with a few tweaks.

I'm trying to find the location of this, do you have the path of where this user variable should be changed in the yaml?

[Alex-Welsh]

You can change this line here: https://github.com/stackhpc/a-universe-from-nothing/blob/stable/2023.1/etc/kayobe/seed.yml#L7C2-L7C21
Which will typically be at ~/kayobe/config/src/kayobe-config/etc/kayobe/seed.yml. I think it will need to be rocky.

Changing that line will get you further, however I suspect that you'll hit more issues later. I'm assuming the host machine you are using is CentOS 8? The easiest solution would be to rebuild using Rocky 9.

Setting os_distribution: "rocky" and os_release: "9" under globals.yml may be enough to make it work with CentOS.

My host machine is Debian 12. What I did was changing this line to the user 'admin'. Then it continued. But I suppose that's an ugly hack for now? Or maybe a wrong user? Or even wrong host distribution?

[Alex-Welsh]

Debian 12 is very much uncharted territory. You can try setting the *_bootstrap_user variables in seed.yml, compute.yml and controllers.yml to admin if that seems to work for you.

The two host distributions supported by kayobe are Ubuntu 22.04 and Rocky 9. docs link
If possible I'd recommend switching to one of those two and use a big VM or similar
