Problem:

UEFI HTTPboot provisioning fails with 404s when trying to install Rocky 9.7

Expected outcome:

Provisioning loads necessary files and starts to install the OS

Foreman and Proxy versions:

Both 3.17.0

Foreman and Proxy plugin versions:

  • foreman-tasks: 11.0.6
  • foreman_remote_execution: 16.3.1
  • katello: 4.19.0.1

Distribution and version:

I assume this means the Foreman server: Rocky 9.7

Proxy log output:

For some reason the client is trying to get files rooted in /EFI instead of /httpboot.
However, the files it’s looking for aren’t there anyway.
I did find them in /usr/lib/grub/x86_64-efi so I could put them in the foreman-proxy’s web root, but I can’t figure out where that is.

One other thing I just noticed, this message in the Grub client output:

Click on 'Build PXE Default' in the Foreman interface
to create the default global grub.cfg configuration.

However I can’t find this to click on in the Foreman interface.

I think you might be looking for this item:
Hosts / Templates / Provisioning Templates

Thanks, I have clicked that and it says the default is set.
Now when I try to do the OS install it just drops to a grub prompt.

The proxy logs just show grub being downloaded:

This is the grub.cfg for the server I’m trying to install:

Another thing I’ve noticed is if I try to curl the inst.ks URL, it is “Not found”. There must be something I’m missing on the Foreman config, but it’s proving very hard to troubleshoot.

$ curl http://foreman.sjcvirt.rti.com:8000/unattended/provision?token=4202f094-91ad-40b2-a548-7f1a77454e7f
