系统篇： ubuntu 18.04 更换国内软件源

1、备份原本的软件源文件

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

2、删除原本的软件源

sudo vim /etc/apt/sources.list

3、添加软件源

• 清华源

# 默认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
deb / bionic main restricted universe multiverse
# deb-src / bionic main restricted universe multiverse
deb / bionic-updates main restricted universe multiverse
# deb-src / bionic-updates main restricted universe multiverse
deb / bionic-backports main restricted universe multiverse
# deb-src / bionic-backports main restricted universe multiverse
deb / bionic-security main restricted universe multiverse
# deb-src / bionic-security main restricted universe multiverse# 预发布软件源，不建议启用
# deb / bionic-proposed main restricted universe multiverse
# deb-src / bionic-proposed main restricted universe multiverse
