ubuntu 12.04上面安装java jdk

记得之前把虚拟机弄好了啊，怎么执行java -version又不行了呢。

sudo apt-get install sun-java6-jre执行

出现Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
root@vivi:/opt# sudo apt-get update
E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)

细看环境变量，我安装的版本明明是jdk1.6.0-38怎么成31了，看来这个地方配置要进行改动，ok了
