Ubuntu 7.10修改软件源的方法

安装好ubuntu 17.10后，我们发现使用apt-get 安装软件时特别慢，所以需要更换一下软件源。

方法：

1.备份自带源

sudo cp /etc/apt/sources.list ~/sources.list.bak

2.修改源：

把以下内容贴到/etc/apt/sources.list文件中：

# deb cdrom:[ubuntu 17.04 _zesty zapus_ - release amd64 (20170412)]/ zesty main restricted

# see http://help.ubuntu.com/community/upgradenotes for how to upgrade to
# newer versions of the distribution.
deb http://mirrors.aliyun.com/ubuntu/ artful main restricted
# deb-src http://us.archive.ubuntu.com/ubuntu/ zesty main restricted

## major bug fix updates produced after the final release of the
## distribution.
