Getting permission denied (public key) on gitlab
<p>My problem is that I can't push or fetch from GitLab. However, I can clone (via HTTP or via SSH). I get this error when I try to push :</p>

<blockquote>
  <p>Permission denied (publickey) fatal : Could not read from remote repository</p>
</blockquote>

<p>From all the threads I've looked, here is what I have done :</p>

<ul>
<li>Set up an SSH key on my computer and added the public key to GitLab</li>
<li>Done the config --global for username and email</li>
<li>Cloned via SSH and via HTTP to check if it would resolve the issue</li>
<li>Done the ssh -T git@gitlab.com command</li>
</ul>

<p>If you have any insight about how to resolve my issue, it would be greatly appreciated.</p>
