我在服务器上安装gitlab。使用web-browser添加公钥。
在authorized_keys中添加公钥。
当我连接到服务器whithin ssh时，服务器询问密码（为什么？）。当我尝试克隆repo时使用ssh，服务器请求密码，但每次传递失败（root，my_gitlab_login，main_server_user）！跨越http工作！
我想在没有密码的情况下工作，当我连接到服务器whithin ssh时，以及当我尝试克隆git-repo时。

尝试ssh-agen，ssh-add并重新生成密钥 - 无法正常工作（

您是否尝试通过复制粘贴生成authorized_keys文件？根据我的经验，使用scp将公钥复制到authorized_keys文件中会产生差异：
scp -P <port number> -i <identity key> <local source file> <vm-user@ip:/destination directory and file>
