根据目前的系统修改相应的源信息:
deb https://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
2.备份修改配置文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup //备份
sudo vi /etc/apt/sources.list //操作文件
ggdG //删除原有信息
// 添加源信息
3.阿里源
# https://opsx.alibaba.com/mirror
deb https://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
# 仿照清华镜像源，注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
