无论如何，当不再支持 Ubuntu 的发行版时，是否可以从命令行中得知？我正在寻找这样的东西，（不使用谷歌或维基百科），
apt-release-support xenial
或者，即使它只是告诉我我的发行版是否受支持。

运行ubuntu-support-status将告诉您已安装的所有内容的支持持续多长时间，以下是我的输出作为示例：

You have 14 packages (0.6%) supported until January 2022 (5y)

2021 年 7 月 11 日编辑：
在较新版本的 Ubuntu 中（在 20.04 上验证）ubuntu-support-status已被替换为ubuntu-security-status
$ ubuntu-security-status
2553 packages installed, of which:
2073 receive package updates with LTS until 4/2025
467 are receiving security updates with ESM Apps until 4/2030
10 packages are from third parties
3 packages are no longer available for download
Packages from third parties are not provided by the official Ubuntu
archive, for example packages from Personal Package Archives in
Launchpad.
For more information on the packages, run 'ubuntu-security-status
--thirdparty'.
Packages that are not available for download may be left over from a
previous release of Ubuntu, may have been installed directly from a
.deb file, or are from a source which has been disabled.
For more information on the packages, run 'ubuntu-security-status
--unavailable'.
