John the ripper typing error

I’m wading to the cybersecirity training labs. theres a lab with john the ripper typed into the command line. John the ripper commands fail repeatedly. I’ve checked for typos and errors and entered the command four times over. I’m stuck at this lab and would like to move forward. any ideas?

Which lab and lab steps are you trying to complete?

Can you show a screen shot showing the command(s) you are trying and the output?
