我读了“apt-get install”什么时候会要求我确认是否继续？（2013年）：
出现以下情况时出现提示：
- 将安装额外的软件包（除了您要求安装的软件包 - 例如依赖项）
- 必要的软件包将被删除。这里的 Essential 被定义为系统上必须始终可用且可用的最小功能集，即使包处于未配置（但未打包）状态时也是如此。使用 Essential 控制字段将软件包标记为系统必需的。
- 更改保留的包裹
然而，在我的 Linux Mint 20.2 上，我现在注意到apt/apt-get显示了删除非必需软件包和安装命令行提供的软件包的确认信息。与 2013 年相比，2021 年 apt 确认的当前要求是什么？
