如何判断 apt-get upgrade 或 apt-get dist-upgrade 上次运行的时间

有没有一种干净的方法来检测 apt-get upgrade 或 apt-get dist-upgrade 上次在 Ubuntu 服务器上运行的时间？

如果没有默认方法执行此操作，那么修改脚本的最佳位置是哪里，以便跟踪 apt-get upgrade 或 apt-get dist-upgrade 上次运行的时间。

答案2

对于“我们上次修补这个问题是什么时候？”这个问题，我们能找到一个更简单、更准确的答案，这对我们来说很有用。所以我把这些放在一起。我在 12.04、14.04 和 16.04 上进行了测试。它为这个问题提供了相当准确的答案。

注意：“合理准确”可能并不意味着“完全准确”。

注意：仅针对该问题。
