title: Broken gpg key from google kubernetes kubectl
body: <p>So I'm trying to install kubectl from the official repository but I'm getting an error while adding their key: <a href="https://packages.cloud.google.com/apt/doc/apt-key.gpg" rel="nofollow noreferrer">https://packages.cloud.google.com/apt/doc/apt-key.gpg</a> . </p>
  
  <p>I've tried <code>user@machine:~/Downloads$ gpg --verify apt-key.gpg 
  gpg: verify signatures failed: Unexpected error</code></p>
  
  <p>Is it a bad key for you also? I'm using a DeepinOS for the first time so perhaps it's some internal issue?</p>
