title: Docker Desktop doesn't install saying docker-ce-cli not installable
body: <p>In an online training course, the instructor mentioned that he has &quot;an Ubuntu virtual machine installed with Docker Desktop&quot;; therefore, I am trying to install the same on a Windows 10 physical host following the <a href="https://docs.docker.com/desktop/linux/install/ubuntu/#install-docker-desktop" rel="noreferrer">instructions</a> on the official website.</p>
  <p>However, the <code>apt-get install</code> didn't work, and the error message was <code>docker-desktop : Depends: docker-ce-cli but it is not installable</code>. I am wondering whether I missed anything here.</p>
  <p>We highly appreciate any hints or suggestions. Just let me know if you need more details.</p>
