Encountering a lot of issues and I cannot upgrade/update my system also my OS change to Proxmox VE!

After installing pimox7 automatically followed the tutorial, I'm encountering a lot of error like cannot access the web-cli and I cannot update & upgrade my RPI 4 model B also my OS change into Proxmov VE 7.2-7 aarch64. I followed the instructions for uninstallation too but I'm still encountering the same issue as I cannot update & upgrade my system also my OS is still Proxmov VE 7.2-7 aarch64.
