正确修复（标准做法，一步到位）
✅ 1. 添加 Docker 官方仓库
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg -y
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
✅ 2. 添加 repo
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/ubuntu \
(. /etc/os-release \&\& echo VERSION_CODENAME) stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
✅ 3. 安装 compose plugin
sudo apt-get update
sudo apt-get install docker-compose-plugin -y
✅ 4. 验证
docker compose version
✅ 5. 运行
docker compose up -d
