Command line is not working in Labs,
The labs are of 2 tier application form devops pre-requisite course
What happens if you open another terminal?
This appears to be a problem in multiple labs (@al1 – see the bug queue). It takes almost 4 minutes for the cursor to become available on this lab, as on some of the others I’ve seen. I’ll add this lab to the list 
This has now been fixed; the command prompt comes up immediately now.
