问题

按照官方教程安装CS50 Library时会报错提示：

worable@deepin:~$ curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | sudo bash

This usually happens if your operating system is not supported by 
packagecloud.io, or this script's OS detection failed.

You can override the OS detection by setting os= and dist= prior to running this script.
You can find a list of supported OSes and distributions on our website: https://packagecloud.io/docs#os_distro_version

For example, to force Ubuntu Trusty: os=ubuntu dist=trusty ./script.sh

If you are running a supported OS, contact the owner of this repository/package for further support.

注意最后一句For example, to force Ubuntu Trusty: os=ubuntu dist=trusty ./script.sh，它让我们伪装成Ubuntu再安装，那么我们输入：

su

进入root账户后再输入：

curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | os=ubuntu dist=focal bash

然后就安装成功了！！

root@deepin:/home/worable/Documents/code# curl -s https://packagecloud.io/install/repositories/cs50/repo/script.deb.sh | os=ubuntu dist=focal bash
