title: WebDriverException: Message: Service chromedriver unexpectedly exited. Status code was: 127
body: <p>I'd like to construct my crawler using selenium on my server.</p>
  
  <p>Thus I had installed/download required dependencies- such as chromedriver, chromium-browser etc on my Ubuntu17.10 server</p>
  
  <p>However, when I run following code:</p>
  
  <pre><code>driver = webdriver.Chrome()
  </code></pre>
  
  <p>It returns following error:</p>

  <p>What does it mean that it's excited..? </p>
  
  <p>I can't get what the original intention of that error code and where to start to fix it.</p>
  
  <p>It looks very rare case.</p>
  
  <p>Maybe relevant:</p>
  
  <p>I had install ubuntu desktop 17.10 on my desktop but failed to get GUI boot. Thus I am just using terminal only, but it well works so far.
  I had installed ssh and remote controlling jupyter notebook from my mac to server desktop, and those errors comes from it.
  Hope this info is relevant to solve this error, otherwise will abort it.</p>
