Multipass的Ubuntu20.04中libgdal-dev的安装

1. 更新apt-get的源为国内源

自带的apt-get源，下载速度慢。最好更新为国内源。
要更新为国内源，需要编辑配置文件/etc/apt/sources.list。

$ sudo vim /etc/apt/sources.list

安装的Ubuntu的版本为20.04，需要找到与版本相匹配的国内源。

# 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-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

在更新国内源时，需要注意国内源所提供的版本是否与安装的Ubuntu一致。否则会出现无法安装的问题。
