六、apt-get的更新及ssh下载安装

进入root用户，root@linux~#输入cp /etc/apt/sources.list /etc/apt/sources.list_backup
root@linux~# cd /etc/apt/
root@linux~#/etc/apt# ll
root@linux~#/etc/apt# vim sources.list
进入以后,用：%s/hk-archive/old-releases回车把所有网址(紫色部分)的ubuntu前面的单词hk-archive改成old-releases,所有都改
(注意还需要%s/security.ubuntu/old-releases回车改完)
:wq!保存后输入
root@linux~#/etc/apt# apt-get update 就能下载了！
root@linux~#/etc/apt# apt-get install openssh-server 下载ssh验证;
root@linux~#/etc/apt# /etc/init.d/ssh start 启动ssh的服务;
