树莓派（ARM64 架构）Ubuntu 24.04 (Noble) 系统 `apt update` 报错解决方案

以下是针对树莓派（ARM64 架构）Ubuntu 24.04 (Noble) 系统 apt update 报错的最终解决方案总结：

问题原因

初始错误 (Transaction was already aborted)：APT 缓存损坏或镜像源同步问题
后续错误 (404 Not Found for binary-arm64)：ARM64 架构误用了仅支持 AMD64 的 ubuntu 镜像源

最终解决方案

步骤 1：备份原配置

bash 复制代码

sudo cp /etc/apt/sources.list.d/ubuntu.sources /etc/apt/sources.list.d/ubuntu.sources.bak

步骤 2：修改为 ARM64 适用的 Ubuntu Ports 国内源

bash 复制代码

sudo tee /etc/apt/sources.list.d/ubuntu.sources << 'EOF'

步骤 3：清理缓存并更新

bash 复制代码

sudo rm -rf /var/lib/apt/lists/*
sudo apt clean
sudo apt update

关键要点

项目	说明
适用架构	ARM64 / aarch64（树莓派、ARM 服务器等）
镜像源关键区别	必须使用 `ubuntu-ports` 而非 `ubuntu`
推荐国内镜像	阿里云 `mirrors.aliyun.com/ubuntu-ports/`
其他可选镜像	清华 `mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/`、中科大 `mirrors.ustc.edu.cn/ubuntu-ports/`

验证命令

bash 复制代码

# 确认系统架构
dpkg --print-architecture  # 应输出: arm64

# 确认 apt 正常工作
sudo apt update && sudo apt upgrade -y
