如何更新,也可以等熟
悉了linuxcāo作后再更新,但是更新源至少有以下两点好处:
a.在线安装或升级时,不需要系统光盘
b.可以在线安装更多更新的软件
源是apt-get要寻找和安装软件的软件库,以文件形式保存在/etc/apt/sources.list,更新源也就是将原来sources.list
里的内容全部删除,替换上其它的源,方法如下:
sudo cp /etc/apt/sources.list /etc/apt/sources.backup
sudo gedit /etc/apt/sources.list
sources.backup,第二步用gedit编辑器编辑sources.list,将里面的内容全部删除,换上如下内容:
deb http://cn.archive.ubuntu.com/ubuntu dapper main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu dapper-security main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu dapper-updates main restricted universe multiverse
