如何解决“sign_and_send_pubkey:签名失败:代理拒绝操作”?

用SSH密钥配置一个新的数字海洋液滴。当我运行ssh-copy-id时，这是我得到的:

ssh-copy-id user@012.345.67.89
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
sign_and_send_pubkey: signing failed: agent refused operation
user@012.345.67.89's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'user@012.345.67.89'"
and check to make sure that only the key(s) you wanted were added.

然而，当我尝试ssh时，会发生这种情况:

ssh user@012.345.67.89
sign_and_send_pubkey: signing failed: agent refused operation
user@012.345.67.89's password:

输入密码后，我可以正常登录，但这当然违背了创建SSH密钥的初衷。我决定看看ssh-agent服务器端，下面是我得到的:

user@012.345.67.89:~# eval `ssh-agent -s`
Agent pid 5715
user@012.345.67.89:~# ssh-add -l
The agent has no identities.

用户/。Ssh /authorized_keys也包含Ssh -rsa密钥条目，但是find name "keynamehere"没有返回任何内容。

当前回答

这可能导致1password不支持ssh-rsa密钥交换。出于安全考虑，它们支持更新的rsa-sha-512和rsa-sha-256。

其他回答

我曾经遇到过和你一样的问题，我通过以下步骤解决了它。

Chmod 700 ~/.ssh Chmod 600 ~/.ssh/* ssh-copy-id user@ip ssh-agent - s ssh-add

对于这个错误:

# git pull
sign_and_send_pubkey: signing failed: agent refused operation
git@github.com: Permission denied (publickey).    
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

在Github帐户>配置文件> ssh中再次验证或添加公钥。

我是这样解决的:

# chmod 400 ~/.ssh/id_rsa

# ls  ~/.ssh/id_rsa -ls  
4 -r--------. 1 reinaldo reinaldo 1679 Jul 26  2017 /home/reinaldo/.ssh/id_rsa

# git pull

这里工作的是:在客户端上

1) ssh-add

2) ssh-copy-id user@server

密钥已经在一段时间前使用简单的“ssh-keygen -t rsa”创建我看到了错误消息，因为我没有首先运行ssh-add就将ssh公钥从客户端复制到服务器(使用ssh-id-copy)，因为我错误地认为我已经在一段时间之前添加了它们。

对我来说，问题在于错误地将公钥复制/粘贴到Gitlab中。复制产生了额外的回报。确保你粘贴的是一行键。

在客户端机器上运行SSH -add，将SSH密钥添加到代理。

使用ssh-add -l(同样在客户端上)确认确实添加了它。
