我在此之前做了以下步骤
检查ssh代理
$ ps aux |grep ssh
7236 1 7236 7236 ? 1138370 18:26:09 /usr/bin/ssh-agent
通过设置将公钥id_dsa.pub添加到github帐户
MyUser@PC000009416062 ~/.ssh
$ ssh -v -T git@github.com

我在这个论坛上尝试了几个解决方案，但没有运气。
我正在使用Cygwin来执行此操作
答案 0 :(得分：4)
debug1：跳过ssh-dss键/home/MyUser/.ssh/id_dsa PubkeyAcceptedKeyTypes
您生成了dsa密钥，默认情况下不支持该密钥。你需要添加
PubkeyAcceptedKeyTypes +ssh-dss
进入~/.ssh/config，或者生成标准RSA密钥，无需解决问题。
答案 1 :(得分：2)
因为您似乎使用的是dsa而不是默认的rsa。你需要在ssh客户端配置中添加一行来启用它。
下面的是我从此demo
中检索到的消息rsa支持默认启用，但dsa / dss支持由以下内容启用：
在ssh客户端中添加行＆＃34; config＆＃34;文件。
PubkeyAcceptedKeyTypes ssh-ed25519,ssh-rsa,ssh-dss,ecdsa-sha2- 命名配置文件＆＃34; config＆＃34;并将其放在Windows的用户主目录/ .ssh中。 /users/myname/.ssh/config
in the current build, the client config file is to be named ssh_config instead of "config"sshd服务器端还应该在sshd_config文件中包含以下条目： PubkeyAcceptedKeyTypes ssh-ed25519，ssh-rsa，ssh-dss，ecdsa-sha2 进行这些更改后重新启动sshd服务器
