现在的关键问题是：你的系统 无法连接 Docker 官方仓库，导致 docker-compose-plugin 无法被安装。主要是因为这个错误：

Could not handshake: Error in the pull function. [IP: 3.168.86.51 443]

这通常是由于：

• 网络问题（GFW/防火墙/代理）

• Docker 源被墙或不通

✅ 快速解决办法（推荐）：直接下载官方 docker-compose 二进制文件

这样你不依赖 apt 和 Docker 仓库，绕过网络问题。按以下步骤操作：

1. 下载 docker-compose 二进制

sudo curl -L "https://github.com/docker/compose/releases/download/v2.20.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2. 添加执行权限

sudo chmod +x /usr/local/bin/docker-compose

3. 验证安装

docker-compose version

这将让你使用传统的 docker-compose 命令，功能和 docker compose 插件一样。

❓可选后续：修复 Docker 官方源连接问题

如果你希望恢复通过 APT 安装 Docker 组件，可以尝试：

1. 用国内镜像加速器（如清华或阿里）

将 Docker 源替换成清华源：

echo "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt-get update

然后再尝试安装：

sudo apt-get install docker-compose-plugin

需要我帮你一键修复源或继续用二进制方式，都可以。你可以先试下载 docker-compose 二进制，那是最快的路径。是否继续？
