我最近按照本指南使用 Gitlab 設定了本機測試伺服器https://www.digitalocean.com/community/tutorials/how-to-set-up-gitlab-as-your-very-own-private-github-clone
我正在嘗試使用我在 Gitlab 介面中建立的管理員帳戶進行第一次提交。我已經添加了我的公鑰，它是我在客戶端電腦上產生的唯一密鑰。這是我嘗試推送時的輸出：
$ git push -u origin master
Access denied.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
這是我的 auth.log

陷入這種情況，我可以採取哪些措施來嘗試解決這個問題？我在客戶端（mac）和伺服器（Ubuntu 14）上都有root存取權限。
