Today my raspi with HomeAssistant “died”. So I had to do something. So I installed Proxmox on my machine and created a VM for HomeAssistant. Later I´m going to install UmbrelOS as a VM on my Proxmox virtual environment like discussed in the following thread:

With proxmox there is no problem booting… My problem is “solved”.
