Cannot mount AirPort time capsule external drive


First day with my Pi and I am still learning how to use it. I have a problem with connecting to my hard drive on airport time capsule. I know so many people have asked the same question before, but I followed different guides still can’t get it works.
I can see the drive on my other device via the IP address: And I named my hard drive as “PI music” does it matter with the space in-between?
I tried to follow many guides to work with those ssh command but still didn’t working.

Any help?
