我正在尝试编译 Aseprite，但无法安装此过程中所需的软件包：libx11-dev。以下是“sudo apt install libx11-dev”的输出
sudo apt install libx11-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
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
sudo apt install libx11-6
Reading package lists... Done
Building dependency tree
Reading state information... Done
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.
如您所见，它已安装，并且是最新版本 2:1.6.4-3ubuntu0.2。这似乎是所需的版本，如您在第一条消息中看到的那样。第二个“未满足”依赖项也发生了类似的问题。
问题似乎是我持有破损的包裹。我尝试了很多方法来解决这个问题，但据我所知，我没有持有任何破损的包裹。当我尝试：
dpkg --get-selections | grep hold
没有输出。同样，“sudo apt install -f”也没有修复任何问题。
以下是可能有帮助的更多输出

答案1
因此，我通过安装并使用 aptitude 而不是 apt 来安装（sudo aptitude install [packagename]）解决了该问题。这将尝试更彻底地解决问题，然后为您提供解决方案。我拒绝了第一个解决方案，下一个建议是降级依赖项。这修复了所有依赖项，并且软件包能够安装。
我仍然不明白为什么这个问题会发生在我的系统上。安装 Nvidia 驱动程序时也会出现这个问题。我不知道这是我的存储库或 ppa 的问题，还是 sources.list 或类似的东西的问题。
