apt-get 更新/升級列表而不更改任何內容

我想查看哪些軟體包可用於更新/升級，而無需實際更改任何文件，因為有些軟體包我不想更新。那麼是否有可能 apt-get update 例外。

我用apt list --upgradable.

下一個選擇是apt-get --simulate upgrade. （基於@EightBitTony）

以下是不同選項的輸出（希望對某人有所幫助）：

me@machine:~$ apt list --upgradable
   Listing... Done
   kubernetes-cni/kubernetes-xenial 0.7.5-00 amd64 [upgradable from: 0.6.0-00]
   N: There are 3 additional versions. Please use the '-a' switch to see them.

me@machine:~$ apt-get --simulate upgrade
   NOTE: This is only a simulation!
         apt-get 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!
