有时，当我安装东西时，我会收到如下错误：

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:
 package1 : Depends: package2 (>= 1.8) but 1.7.5-1ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

我该如何解决这个问题？

我设置了一个新的 Ubuntu VPS 实例，想知道启动和运行基本 LAMP 堆栈的最简单方法是什么（即需要哪些包，需要调整哪些配置选项，如果有的话，等等）。
