我正在尝试在ubuntu 12.4上安装JDK7。
第一次尝试时，电源消失了，在使用终端下载JDK7的过程中，笔记本电脑关机了，就像我在使用下一个终端命令一样
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
当电源恢复供电并且我尝试再次安装JDK7时，锁出现问题，但是在重新启动计算机后使用以下命令修复了该锁
sudo apt-get install whatever
之后，我尝试使用上面的三个命令再次安装，第一个没有错误，第二个也完成了，
但是第三个命令成功下载了软件包，但是出现了错误

Oracle JDK 7 is NOT installed.
dpkg: error processing oracle-java7-installer (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
oracle-java7-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)
我搜索了此错误的解决方案并找到了一些，并尝试了以下说明
sudo rm /var/lib/dpkg/info/oracle-java7-installer*
sudo apt-get purge oracle-java7-installer*
sudo rm /etc/apt/sources.list.d/*java*
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
再次尝试，但出现相同的“未安装Oracle JDK7”错误。
试过了 sudo apt-get -f install
