sudo apt-get purge //常规卸载

sudo apt-get autoremove // 自动清理一些程序

sudo apt-get autoclean

dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P XXX //删除不需要的配置文件

sudo apt-get update //更新本地缓存文件

man -k ssh

　　git config --global user.name "yourname"   //设置Git的user name和email

　　git config --global user.email "youremail"

　　// after these steps,生成SSH密钥

　　// cd ~/.shh 查看是否已经有了ssh密钥

　　ssh-keygen -t rsa -C “youremail”  // 生成密钥

按3个回车，密码为空

最后得到了两个文件：id_rsa和id_rsa.pub

在github上添加ssh密钥,这要添加的是“id_rsa.pub”里面的公钥
