新装系统，登录git服务器clone，突然报这个错误，以前从来没有碰到过，解决过程如下：
seaside@vmdev:~/csdn_git/mcp$ git clone git@gitcode.net:huyongfu2004/mcp.git Cloning into 'mcp'... /etc/ssh/ssh_config: line 54: Bad configuration option: permitrootlogin /etc/ssh/ssh_config: terminating, 1 bad configuration options fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
打开配置文件：
sudo vim /etc/ssh/ssh_config
permitrootlogin这个配置应该 放到sshd_config（服务器段配置）中，ssh_config是客户端配置，找到最后一行，所以直接把这行去掉或者注释掉就OK了
# PermitRootLogin yes
