我如何找出哪些软件包未升级，以及原因是什么？
在许多类似的输出中这，它还会打印类似的内容The following packages have been kept back:，但在我的情况下不是这样。
此外：
$ sudo apt list --upgradable

apt-cache policy日志这里。
答案1
不会被升级的两个软件包已被固定，以防止它们被升级。
从输出的末尾apt-cache policy：
Pinned packages:
nsight-compute -> 10.1.243-3 with priority -1
nsight-systems -> 10.1.243-3 with priority -1
