更新日誌
- 2019-11-24: 腳本開發完成，僅支持buster版本系統，添加國內主要的樹莓派源地址
部署說明
由於樹莓派默認源下載速度慢，所以開發該腳本，用於更換國內源，作者目前已將國內幾家主流的樹莓派源添加至配置列表config/website.list，具體使用方法下述有相關說明。
更換源
打開文件夾，運行 run.sh 腳本
./run
運行結果如下：
Start executing the script.
Step 1: Get the system version code.
VERSION_CODENAME=buster
Step 2: Determine whether to connect to the network?
[OK] The network is connected.
Step 3: Determine if a profile exists.
[Exist] website list file: /home/pi/raspi_source_change/config/website.list
