title: Can't clone Git Repository, even I added Public Key to GIthub
body: <p>I bought a new M1 Macbook Air, and I started to setup my on laptop. I installed Git, and I cloned my repository with</p>
  <pre><code>git clone git@github.com:xibotlab/homepage.git
  </code></pre>
  <p>Then there was an error:</p>
  <pre><code>git@github.com: Permission denied (publickey).
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  </code></pre>
  <p>I knew that to solve this error I must add Git Public Key to Github, so I entered this:</p>
  <pre><code>ssh-keygen -t ed25519 -C &quot;xibotmoon@gmail.com&quot;
  </code></pre>
  <p>and I added Public Key to Github successfully.</p>
  <p>But even I added Public Key, there was an error above. I searched on Github but I couldn't solve this problem, because all documents saids I must add Public Key, and I already did! How do I solve this?</p>
  <p>Thank you.</p>
