Stakepool setup prereqs.sh not creating folder structure

Hi there, I am trying to set up a stakepool by following the guidelines on this site and it seems that once I get to the step of running prereqs.sh, the folder structure never generates. The OS dependancies download and install, but when the folder structure is generated it says downloading files and then nothing happens. Any clue why this might be happening?

There are only 4 commands, am I missing something blatantly obvious??
I have set up a passwordless sudo user on a fresh ubuntu VM and run:
mkdir “$HOME/tmp”;cd “$HOME/tmp”
curl -sS -o prereqs.sh https://raw.githubusercontent.com/cardano-community/guild-operators/master/scripts/cnode-helper-scripts/prereqs.sh
chmod 755 prereqs.sh
./prereqs.sh -f

Viewing the script doesn’t give me any clues as to why its not working

Did you installed curl as required?

CentOS / RedHat - sudo dnf -y install curl
Ubuntu / Debian - sudo apt -y install curl
