I installed a freshly downloaded version of proxmox VE 8.3-1 and tried to run the post install script
bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/misc/post-pve-install.sh)" from https://tteck.github.io/Proxmox/#proxmox-ve-post-install
unfortunately, it failed and I got the message.
"✗ This version of Proxmox Virtual Environment is not supported
Requires Proxmox Virtual Environment Version 8.0 or later."
