Ubuntu 20.04 更换国内apt源
第一步：备份源文件：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup第二步：编辑/etc/apt/sources.list文件
在文件最前面添加以下条目(操作前请做好相应备份)：
sudo vi /etc/apt/sources.list# 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-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse

# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse第三步：执行更新命令：
sudo apt-get update
sudo apt-get upgrade常用国内源：
