Where is [] 12 13 14 15 to fill up the 15 character requirement

I do not see it and the terminal says that us connecting, but nothing
happens so I can’t enter the cd /home/user/catkin_ws/src command.
The text gets typed under the “Your topic is similar…”
None of the answers are helpful. If I can’t get started and there is no
useful help, I see not reason to continue.
Having to supply 15 characters is not helpful,

Hi @chuck.untulis,

Welcome to our community.

I couldn’t get which part of the course you are referring to.

Could you elaborate better your question, explaining what is asked in which part of the course, and then tell us which commands you tried and what are the error messages?

I look forward to hearing from you.
