git拉取代码报错

no matching host key type found. Their offer: ssh-rsa,ssh-dss

git拉取代码报错如下

$ git clone ssh://git@xxx.com/xxx/xxx.git
Cloning into 'xxx'...
Unable to negotiate with 10.10.10.10 port 6666: no matching host key type found. Their offer: ssh-rsa,ssh-dss
fatal: Could not read from remote repository.

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

原因

这个错误说明你的 Git 客户端尝试连接远程仓库时，无法协商使用合适的 SSH host key 类型。远程服务器只支持 ssh-rsa 和 ssh-dss，但你的本地 SSH 客户端默认禁用了这类旧算法

解决方法

允许 ssh-rsa ，参考 stackoverflow

$ cat ~/.ssh/config
Host xxx.com
	PubkeyAcceptedAlgorithms +ssh-rsa
	HostKeyAlgorithms +ssh-rsa
