以Ubuntu16.04為例：

1. 備份原有軟件源文件

cp /etc/apt/sources.list /etc/apt/sources.list.bak_yyyymmdd

?

2. 打開sources.list文件，在文件末尾增加如下軟件源地址

vi /etc/apt/sources.list

追加如下地址：

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

3. 更新系統(tǒng)軟件源

執(zhí)行命令，更新系統(tǒng)軟件源地址

apt-get update apt-get upgrade

4. 其他軟件源
