title: Apt-get is broken after install Google Cloud SDK on Ubuntu 18.04 LTS
body: <p>I was installing the Google Cloud SDK on my Ubuntu VM using the following commands</p>
  
  <pre><code># Add the Cloud SDK distribution URI as a package source
  echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] http://packages.cloud.google.com/apt cloud-sdk main" | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list
  
  # Import the Google Cloud Platform public key
  curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key --keyring /usr/share/keyrings/cloud.google.gpg add -
  
  # Update the package list and install the Cloud SDK
  sudo apt-get update &amp;&amp; sudo apt-get install google-cloud-sdk
  </code></pre>
  
  <p>and I think its broken now. </p>
  
  <pre><code> apt-get install unixODBC unixODBC-dev
  E: Conflicting values set for option Signed-By regarding source https://packages.cloud.google.com/apt/ cloud-sdk: /usr/share/keyrings/cloud.google.gpg != 
  E: The list of sources could not be read.
  E: Conflicting values set for option Signed-By regarding source https://packages.cloud.google.com/apt/ cloud-sdk: /usr/share/keyrings/cloud.google.gpg !=

  </code></pre>
  
  <p>Is there anyway to fix it so I can continue to download packages. </p>
