When installing ISPConfig on Ubuntu 18.04 minimal using the newest automated installation script in Google Cloud, I got the following message: "Error: Could not reach (the ispconfig site), please check your internet connection and run this script again." This message is nonsense. It appears because the setup script tries to ping ispconfig.org, but ping is not installed. Install ping first: apt-get update apt-get install inetutils-ping After that, the script will start and run fine.
