hi, i tried to install this cript on latest version of proxmox (8.3.2)

wget https://raw.githubusercontent.com/extremeshok/xshok-proxmox/master/networking/network-configure.sh -c -O network-configure.sh && chmod +x network-configure.sh
./network-configure.sh && rm network-configure.sh

and i get error:
