三星笔记本电脑 Ubuntu 可以看到 wifi 但无法连接

我知道周围有成千上万个这样的问题，但我尝试了几个，没有得到任何结果，所以我决定提出一个新问题。 NetworkConnections 可以看到 wifi 连接，但没有连接，而且我看不出有办法告诉它手动连接。

我想在不使用有线连接的情况下解决这个问题，因为我在大学使用这台笔记本电脑，并且也想在那里使用 Wi-Fi。

以下是实用工具提示建议的一些数据：

答案1

这不是一个包罗万象的答案，但就我而言，我能够在检查评论中 AzkerM 的问题时以某种方式解决问题：

  1. 我尝试运行sudo apt-get install g++来检查是否可以安装某些东西。
  2. 结果是E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
  3. 我这样做了，并尝试再次运行 g++ 安装。
  4. ???（就我而言，奇迹发生了，不知道是什么发生了）
  5. 盈利！（突然有了网络。）

很确定跑步sudo dpkg --configure -a在这里起了作用。
