I have the same issue. It looks like the install script failed. I get

Done! Please reboot your Raspberry Pi now

That is from my 2nd attempt. My first attempt it just rebooted so I didn't see how it ended. I tried to manually copy the html files to /var/www/html. I can now see the interface but nothing really works. I'm sure because there is no binary etc.

I delete cd .. in step 4 and it works. But fail to change it to access point under noobs os

Did anyone get this to work? I'm running into the same issue.
