wireguard installation

Hello all

I am trying to install wireguard on my proxmox 8 server.

I am following a youtube video to install wireguard using the helper scrips at;
root@pve:~#

and i paste the bash crips: bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/wireguard.sh)"

the shell returns the prompt with out installing

What am i missing ?

Thank you and happy holidays to all
