We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue This here seems to be the issue. You are not able to do SSH from the machine in which you are running the script to the host. I am assuming that both should be the same machine. i.e. the machine in which you want to install insights and machine in which you are running the script. If that is the case, see if you can do `ssh localhost` Once `ssh localhost` is successful you should be able to proceed. ---
