新裝了個樹莓派，更新時候發現連不上網，遂換國內源。由於近期AI用習慣了，就沒找官方說明，結果......果然踩雷了。所以還是得看官方提供的說明。
清華開源映象站Raspbian 軟體倉庫
1、檢視系統架構
$ uname -m
aarch64
提示aarch64使用者直接參考 Debian 幫助
Debian 軟體源
大部分 Debian 的軟體源配置檔案使用傳統的 One-Line-Style，路徑為 /etc/apt/sources.list；但是對於容器映象，從 Debian 12 開始，其軟體源配置檔案變更為 DEB822 格式，路徑為 /etc/apt/sources.list.d/debian.sources。一般情況下，將對應檔案中 Debian 預設的源地址 http://deb.debian.org/ 替換為映象地址即可。
Debian Buster 以上版本預設支援 HTTPS 源。如果遇到無法拉取 HTTPS 源的情況，請先使用 HTTP 源並安裝：
sudo apt install apt-transport-https ca-certificates
傳統格式（/etc/apt/sources.list）
