最后我设法在虚拟机上设置了 gitlab 服务器。静态 IP 是 192.168.xx.xx，我从浏览器正常输入到 gitlab dashboar。到目前为止一切都很好。
我还在其他网络服务器上安装了 git 并创建了 git 文件，以便我可以将文件直接推送到 192.168.xx.xx（这是 gitlab 平台）。
我已生成 SSH 密钥 (id_ed25519) 并将它们存储在 /c/users/admin/.ssh/ 中。在这条路上我有
我还将公钥复制到我的 gitlab 帐户中，因此 SHA256 在网络服务器和 gitlab 帐户上是相同的。
我有一个问题，我无法完成我正在做的事情，因为我正面临一个问题。当我运行此命令时：
git clone git@192.168.xx.xx:root/sample.git
我收到一个错误：
Cloning into 'sample'...
git@192.168.xx.xx: Permission denied (publickey).
fatal: Could not read from remote repository.
我在互联网上搜索过，我发现这是一个常见问题，但我几乎尝试了所有方法。创建了文件等，但没有任何效果。
另外，我试过这个命令：
ssh-add /c/users/admin/.ssh/id_ed25519
Could not open a connection to your authentication agent.
我能做什么？

退出状态 0 没问题。现在我的问题是我想用 gitlab 连接 .git 但是当我输入这个命令时：
git clone git@192.168.22.29:user1/devnow.git
它显示密码提示。我有我为此使用的所有密码的字段，但没有任何好的结果。 另外我想说我将 bitnami 与 debian + gitlab 一起使用。我想通过 ssh 登录到 user1，以便访问 gitlab 以查看我的本地存储库。
答案 0 :(得分：1)
首先使用更简单的 rsa 方案尝试使用没有密码短语的密钥进行测试
# register mykey.pub content to your GitLab profile
ssh -i ~/.ssh/mykey git@192.168.22.29
# check you see a Welcome message
如果这不起作用，请尝试使用旧 PEM 格式的密钥：
ssh-keygen -t rsa -m PEM -P "" -f ~/.ssh/mykey
