“未安装Oracle JDK 7”错误？
我正在尝试在ubuntu 12.4上安装JDK7。
在第一次尝试时，电源已经消失，笔记本电脑在使用终端下载JDK7的过程中关机，因为我正在使用下一个终端命令
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer 当电源返回并且我再次尝试安装JDK7时，锁存在问题，但我在重新启动机器后使用以下命令修复了它
sudo apt-get install whatever
之后我尝试使用上面的三个命令再次安装，第一个完成没有错误，第二个也是，
但第三个命令成功下载了包，但出现了错误
Download done. Removing outdated cached downloads... sha256sum mismatch jdk-7u51-linux-i586.tar.gz 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)
我搜索了这个错误的解决方案并找到了一些，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。
尝试过sudo apt-get -f install

不知道如何解决它
请帮忙
提前致谢
在终端上运行以下命令，
sudo dpkg -P oracle-java7-installer sudo apt-get -f install
我有另一个潜在的解决方法，但它需要人工干预。 之所以破坏是因为Oracle希望您接受OTN许可。 这是解决方法：
转到Oracle Java7 JDK下载站点（我在这里找到了它）。 同意OTN协议，然后找到名为“ jdk-7u（whateverupdateislatest）-linux-x64.tar.gz ”的文件
sudo mv jdk-7u67-linux-x64.tar.gz /var/cache/oracle-jdk7-installer/ sudo apt-get install oracle-java7-installer
我认为您的下载已损坏。 你必须首先通过代码删除损坏的包：
sudo apt-get purge oracle-java7-installer
清洁你的apt：
sudo apt clean
删除并重新导入ropsitory：
sudo add-apt-repository --remove ppa:webupd8team/java sudo apt-get update sudo apt-add-repository ppa:webupd8team/java sudo apt-get update
再次安装您的包：
sudo apt-get install oracle-java7-installer
享受它吧！ 如果问题没有解决，请尝试使用VPN。 也许你和oracle网站之间有过滤
检查文件/var/cache/oracle-jdk7-installer/jdk-7u51-linux-*.tar.gz
如果它很小（~5000字节） – 那么它包含告诉您接受OTN许可证的文本。
如果可以，请切换到oracle-java8-installer
