SSH不支持ssh-dss的解决方案（Skipping ssh-dss key: ........... not in PubkeyAcceptedKeyTypes）

今天手贱，升级了自己的mac系统，结果git无法从远程服务器拉取代码了，报错：

bogon:aaa$ git pull
[email protected]: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
fatal: Could not read from remote repository.

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

然后我试了下ssh，一样是Permission denied，

于是我使用ssh  -v参数查看了下过程：

bogon:.ssh yodo1$ ssh -v [email protected]
OpenSSH_7.8p1, LibreSSL 2.7.3
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 48: Applying options for *

debug1: Connection established.

debug1: Trying private key: /Users/yodo1/.ssh/id_xmss
debug1: No more authentication methods to try.

 查询了一下，好像现在ssh不推荐使用dsa加密的秘钥，但是处于一些原因无法更换，所以：

1.打开ssh_config文件：

vim /etc/ssh/ssh_config

2.将如下设置添加到ssh_config末尾：

PubkeyAcceptedKeyTypes +ssh-dss

3.保存后，执行ssh 登录，使用正常。
