查找 Ubuntu 团队不支持的已安装软件包

Question

根据/etc/apt/sources.list“Ubuntu 团队完全不支持” ，如何检查我是否安装了任何 Universe 或 Multiverse 软件包？
我正在寻找的是 Ubuntu 18 LTS 服务器（无 GUI）的命令行，用于按组件列出已安装的软件包，包括不可用的已安装软件包apt-get（不是 中配置的档案的一部分/etc/apt/sources.list）。
aptitude versions '?name(.)'列出可用的包及其安装状态，但不输出它们的源组件，也不输出apt-cache.

您可以使用ubuntu-support-status命令

$ ubuntu-support-status --help
Usage: ubuntu-support-status [options]

Options:
  -h, --help          show this help message and exit
  --show-unsupported  Show unsupported packages on this machine
  --show-supported    Show supported packages on this machine
  --show-all          Show all packages with their status
  --list              Show all packages in a list

带有相应的参数--show-unsupported。

以下是我的 16.04.5 LTS 系统的示例：

$ ubuntu-support-status --show-unsupported

Support status summary of 'hostname':

You have 94 packages (1.9%) supported until April 2021 (Community - 5y)
You have 2668 packages (54.0%) supported until April 2021 (Canonical - 5y)
You have 647 packages (13.1%) supported until April 2019 (Community - 3y)

You have 79 packages (1.6%) that can not/no-longer be downloaded
You have 1456 packages (29.4%) that are unsupported

No longer downloadable:

... 

Unsupported:
