我正在尝试将服务器应用程序（BaasBox）部署到Google应用程序引擎
BaasBox 需要 java 1.6 或更高版本才能执行。
当我使用 检查虚拟机上的 java 时java -version，我得到以下信息：
The program 'java' can be found in the following packages:
* default-jre
* gcj-4.8-jre-headless
* openjdk-7-jre-headless
* gcj-4.6-jre-headless
* openjdk-6-jre-headless
Try: sudo apt-get install <selected package>
当我尝试安装上面列出的内容时，问题出现了openjdk-7，我收到以下输出错误：
myname@instance-2:~$ sudo apt-get install openjdk-7-jre-headless
