ubuntu添加国内源

安装Ubuntu 18.04后，使用国外源太慢了，修改为国内源会快很多。

修改阿里源为Ubuntu 18.04默认的源

备份/etc/apt/sources.list

#备份

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

在/etc/apt/sources.list文件前面添加如下条目

#添加阿里源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

最后执行如下命令更新源

##更新

udo apt-get update

udo apt-get upgrade

另外其他几个国内源如下：
