当我运行时，sudo apt install libxmu-dev libxi-dev发生以下情况：

您可以使用 来安装它们。它将建议您使用不同的解决方案来解决依赖关系。接受降级所依赖aptitude的软件包的解决方案。libxi-devlibxmu-dev
首先，安装aptitude：
sudo apt install aptitude
然后，使用以下命令安装你的软件包aptitude：
sudo aptitude install libxi-dev libxmu-dev
第一个解决方案是：
Keep the following packages at their current version:
1) libxi-dev [Not Installed]
2) libxmu-dev [Not Installed]

做不是接受这个解决方案。这将不会安装你的软件包。输入n。
下一个解决方案是：
Downgrade the following packages:
1) libxi6 [2:1.7.6-1 (now) -> 2:1.7.5-1 (xenial)]
2) libxmu6 [2:1.1.2-2 (now) -> 2:1.1.2-1ubuntu1 (xenial)]
Accept this solution? [Y/n/q/?]
输入y接受此解决方案。这将降级libxi6和libxmu6，然后安装libxi-dev和libxmu-dev。
