Why do I keep getting errors?

It seems that your client container was stuck.
This happens when user inputs another command while previous command is being executed.
You can recover your client container by the following manual, but it is cumbersome.
If you are executing more than one script simultaneously on one server, your client container most certainly be stuck.

Anyway, how about you try newer script in English?
