Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libx11-dev : Depends: libx11-6 (= 2:1.6.4-3ubuntu0.1) but 2:1.6.4-3ubuntu0.2 is to be installed
              Depends: libxcb1-dev but it is not going to be installed
              Recommends: libx11-doc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

有两个未满足的依赖项。接下来我尝试安装第一个依赖项 libx11-6

libx11-6 is already the newest version (2:1.6.4-3ubuntu0.2).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

可以看到已经安装好了，也是最新版本，2:1.6.4-3ubuntu0.2。正如您在第一条消息中看到的，这似乎是必需的版本。第二个“未满足”的依赖项也会出现类似的问题。

看来问题是我拿着破损的包裹。我已经尝试了很多方法来解决这个问题，但据我所知，我没有拿着任何破损的包裹。当我尝试：

dpkg --get-selections | grep hold

没有输出。同样，“sudo apt install -f”也不能解决任何问题。

这里有更多可能有帮助的输出

在将我的 Ubuntu 从 18.10 升级到 19.04 后，一些软件包被阻止了，但我并不在意，因为我认为这些问题将在几周内得到解决，届时依赖项将升级到适合我的操作系统的正确版本。过了一段时间，这并没有发生，我在这些“被阻止”的包周围戳了一下，发现了一个问题，这也解释了为什么我的系统负载指示器小部件和其他依赖于传感器的小部件停止工作。

只剩下 2 个包裹被扣留：libsnmp30 sysstat. 两者都以一种方式或另一种方式依赖，libsensors5而后者又依赖于libsensors-config. 现在我可以尝试libsensors-config通过安装，sudo apt install libsensors-config但是我得到的（最后一个）输出让我觉得这不是一个好主意，对吧？

谁能建议我在这里做什么？我不知道如果我尝试安装会发生什么，libsensors-config因为它似乎想删除xserver-*, ubuntu-*, *mesa*（不重新安装新版本？）和一大堆其他重要的东西，但我认为这对我的系统...

而且我仍然保留相同的包裹。sudo apt upgrade给我相同的输出sudo apt -f install。

不过现在libsensors5又libsensors-config好像安装了？
