git添加遇到问题 sign_and_send_pubkey: signing failed: agent refused operation Permission denied (publicke

Posted 2021-03-09 clemente

sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).

参考

https://help.github.com/cn/github/authenticating-to-github/error-permission-denied-publickey

https://segmentfault.com/a/1190000008733238

https://www.cnblogs.com/mozq/p/11824468.html

步骤

ssh-keygen -t rsa -C "[e-mail]"

 在本地生成 rsa 公私钥。直接回车。名称必须是默认的id_rsa。

 将公钥保存到 github / gitee

ssh -T [e-mail]

如果正常会返回

Hi XXX! You‘ve successfully authenticated 之类的

 

当然我们这里遇到的是

sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).

此时我们可以执行如下命令:

 

ssh -vT [e-mail]

 

如果看到以下Permission denied (publickey) 结尾

解决办法通过 ssh-add

 

eval "$(ssh-agent -s)"

我们会看到：

Agent pid xxxxx

继续执行

ssh-add

显示如下即成功：

 

Identity added: /home/xxx/.ssh/id_rsa (/home/xxx/.ssh/id_rsa)
