#备忘# 恢复Debian 13默认的APT更新源

之前胡乱瞎弄，结果把apt源弄乱了，结果现在想还原。网上搜了一下，不过最好还是弄之前备份一下。以下是Debian 13的默认apt源

把如下内容粘贴到 /etc/apt/sources.list

deb http://deb.debian.org/debian trixie main contrib non-free non-free-firmware
deb-src http://deb.debian.org/debian trixie main contrib non-free non-free-firmware

deb http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware
deb-src http://deb.debian.org/debian trixie-updates main contrib non-free non-free-firmware

deb http://security.debian.org/debian-security trixie-security main contrib non-free non-free-firmware
deb-src http://security.debian.org/debian-security trixie-security main contrib non-free non-free-firmware

Debian 13也支持新的deb822格式（创建文件 /etc/apt/sources.list.d/debian.sources）
