无法在 Ubuntu 12.04 中安装 Java JDK：损坏的软件包

Question

我尝试输入这个来安装java JDK

 sudo apt-get install openjdk-7-jdk

它用这个回应

Reading package lists... Done
Building dependency tree... 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:
 openjdk-7-jdk : Depends: openjdk-7-jre (= 7u55-2.4.7-1ubuntu1~0.12.04.2) but it is not going to be installed
