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:

libsdl 安装似乎没有成功。在搜索 libsdl 时，有两个版本 libsdl1 和 libsdl2。我正在考虑寻找其他方法来安装它们。有人对安装有什么建议吗？

通过Doug的建议解决了
Open up Software & Updates > Updates tab & make sure that
the first 2 are enabled. (- trusty-security, trusty-updates).
If one or the other wasn't enabled then do so,
after that reload sources & proceed.
谢谢你的解决方案，Doug！感谢所有参与解决这个问题的人，尤其是steeldriver和AB！
答案1
打开“软件和更新”>“更新”选项卡，确保前两个已启用。（- trusty-security、trusty-updates）。如果其中一个未启用，则启用它，然后重新加载源并继续。
如果两者都在，则尝试在主页上切换服务器 > 下载自：使用主服务器。然后重新加载源并查看。
您需要 libsdl1.2-dev (1.2.15-8ubuntu1.1) 才可用，它应该已于 2014 年 4 月发布 -http://packages.ubuntu.com/trusty-updates/libsdl1.2-dev
答案2
尝试类似gcc cube.c $(pkg-config --libs glut gl glu sdl). 但不太确定这些包名称。
