title: ls doesn't show any output in ssh connected to an Debian 9 VM instance in Google Cloud Platform
body: <p>this might be a dumb question, but I checked everywhere and there's no direct answer to it.</p>
  
  <p>I set up both SSH keys successfully and I can connect to my instance via terminal, but when I do "ls", it doesn't show me any output. I am using iTerm2 with zsh on my Mac but I don't think this is an issue.</p>
  
  <p>Can anybody give me a hint? Thanks!</p>
