当使用yum或 时dnf，在要求确认安装或更新软件包之前会显示事务摘要，如下所示：

当使用apt/时apt-get，摘要如下所示：

如你所见，在这种情况下，要安装的版本不明确。如果官方仓库中的最新包不是我需要的，我可能需要添加不同的仓库。所以在这种情况下，我必须apt-cache policy <package>先运行以验证包版本。
我的问题是：此确认的格式是否可以配置？我可以像yum之前一样显示软件包版本吗？
答案1
解决方法是，首先在模拟模式-s。在下面的代码中，我想知道如果我安装的话，我的 Kubuntu 18.04 上会安装什么gedit：
$ apt install -s gedit
NOTE: This is only a simulation!
apt needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
