总结 如何验证 deb 文件是否完整且没有错误？
我下载的 deb 包不完整，安装时会出错。在尝试安装之前，我想检查它是否有效。如如何在安装前检查并验证 deb 包，我可以使用，dpkg-deb --info <deb file>但是这会提供所有信息，但不会在我的文件上显示任何错误。
在我的特定情况下，我有以下文件
# file is actually ~40MB, download the first 27MB
curl -r 0-28208916 https://download.docker.com/linux/ubuntu/dists/jammy/pool/stable/amd64/docker-ce-cli_20.10.21~3-0~ubuntu-jammy_amd64.deb
下面显示了 deb 的信息，但没有报告文件不完整
dpkg-deb --info docker-ce-cli_20.10.21~3-0~ubuntu-jammy_amd64.deb
dpkg-deb 命令的输出，

Description: Docker CLI: the open-source application container engine
Docker is a product for you to build, ship and run any application as a
lightweight container
.
Docker containers are both hardware-agnostic and platform-agnostic. This means
they can run anywhere, from your laptop to the largest cloud compute instance and
everything in between - and they don't require you to use a particular
language, framework or packaging system. That makes them great building blocks
for deploying and scaling web apps, databases, and backend services without
depending on a particular stack or provider.
