My computer is a mini server. And without the HP Agentless Management Service, if I install Proxmox 9, the server doesn't recognize the Proxmox 9 system, which is based on Debian 13. So, for example, the fan runs at 100% and other things...
It should be noted that for version 8.4, there is an HP Agentless Management Service package from Proxmox that runs on Debian 12 and works perfectly. The only drawback is that Proxmox version 8.4 is nearing its end of life, so I need to migrate to version 9.
