pve-bridge fails with status 512

Hello,

I found the guide at https://www.inspectmygadgets.com/set-up-a-home-assistant-vm-on-proxmox/ which pointed me to this repo.

I am running proxmox via KVM on an Ubuntu 22.04 machine, and trying to install hassos. My command is:

bash -c "$(wget -qLO - https://raw.githubusercontent.com/tteck/Proxmox/main/vm/haos_vm.sh)"

I'm getting the following error output:

[INFO] Using local-lvm for Storage Location.
[INFO] Container ID is 101.

Content of /etc/network/interfaces on the proxmox host is:

auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 10.3.37.48/28
        gateway 10.3.37.1
        bridge-ports enp1s0
        bridge-stp off
        bridge-fd 0

Do you have any thoughts on what I could tweak to get this to work? The proxmox install is basically vanilla, no weird customization.

It looks like there's some problem with the network initialization, but I'm not familiar enough with proxmox to debug it on the fly.

Thank you in advance for your advice!

I honestly have no idea where to start with that setup. I've never ran Proxmox that way. Sorry.
I'll move it over to Discussions maybe someone can help
