六、apt-get的更新及ssh下載安裝

進入root用戶，root@linux~#輸入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
進入以后,用：%s/hk-archive/old-releases回車把所有網址(紫色部分)的ubuntu前面的單詞hk-archive改成old-releases,所有都改
(注意還需要%s/security.ubuntu/old-releases回車改完)
:wq!保存后輸入
root@linux~#/etc/apt# apt-get update 就能下載了！
root@linux~#/etc/apt# apt-get install openssh-server 下載ssh驗證;
root@linux~#/etc/apt# /etc/init.d/ssh start 啟動ssh的服務;
root@linux~#/etc/apt# ps -e|grep sshd 驗證是否真正開啟.
