title: ssh/known_hosts: No such file or directory
body: <p>So I'm setting up GitLab and I've encountered a problem along the way. Namely, <a href="https://docs.gitlab.com/ee/user/gitlab_com/index.html#ssh-host-keys-fingerprints" rel="noreferrer">https://docs.gitlab.com/ee/user/gitlab_com/index.html#ssh-host-keys-fingerprints</a> this link calls for adding entries to <code>known_hosts</code>. The problem is, however, that when I'm trying to run a command like <code>/.ssh$ .ssh/known_hosts gitlab.com ssh-ed25519 ...</code> I get this error.</p>
  <p>I've just set up this ssh stuff from scratch.</p>
