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。
