Hello! Some time ago, I ran the go.ispconfig.org script and it has been on the "Installing ISPConfig3" for 40minutes, what should I do?
Try hitting the return key once. Might be that the installer is not stuck but instead your console is not showing you some output and is stuck instead.
It writes a log file that shows where it got stuck. It's really strange, I'm not aware that anyone had such an issue yet. My guess is that your setup somehow prevents the auto-installer can download the ispconfig software or your hard disk is full or you do not have enough RAM. You can also try running the installer with the switch --interactive to do the last parts of the setup in interactive mode.
