我在数字海洋上制作了git服务器并且工作正常，但我想将授权从密码更改为SSH密钥。
现在它对于使用此服务器的SSH / SFTP以及我的pi都很好用。但是git不想合作。
我有：
/home/git/.ssh许可700 /home/git/.ssh/authorized_keys在644 git的shell：/usr/bin/git-shell
在本地计算机上设置.ssh/config以从加密的pendrive加载私钥

答案 0 :(得分：0)
debug1: Trying private key: /home/isaac/secret/server1git Enter passphrase for key '/home/isaac/secret/server1git': debug1: Authentications that can continue: publickey debug1: No more authentication methods to try. Permission denied (publickey).
首先它仍然希望你拥有公钥，所以你也必须创建它。其次，请确保以{root}身份运行ssh。它将解决与Permission denied (publickey)的冲突。
