树莓派改HOST文件解决“curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused”

curl -sSL https://install.pi-hole.net | bash

curl: (7) Failed to connect to raw.githubusercontent.com port 443: 拒绝连接

打开  https://www.ipaddress.com/ 输入访问不了的域名，获得对应的IP。

使用sudo nano  /etc/hosts命令打开不能访问的机器的hosts文件，末尾添加如下内容：

185.199.110.133 raw.githubusercontent.com
185.199.108.133 user-images.githubusercontent.com
185.199.108.133 avatars2.githubusercontent.com
185.199.108.133 avatars1.githubusercontent.com

sudo /etc/init.d/networking restart重启网络，重启终端生效
