“未安装 Oracle JDK 7”错误？

Question

我正在尝试在 ubuntu 12.4 上安装 JDK7。

在第一次尝试中，电源已经消失，笔记本电脑在使用终端下载 JDK7 的过程中关闭，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

当电源恢复并且我再次尝试安装JDK7时，锁定出现问题，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，第一个没有错误完成，第二个也是如此，

但是第三个命令成功下载了包但是出现了错误

Download done.

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，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，但出现了相同的“未安装 Oracle JDK7”错误。

试过了 sudo apt-get -f install

请帮忙

提前致谢

Answer 1

在终端上运行以下命令，

sudo dpkg -P oracle-java7-installer
sudo apt-get -f install

Answer 2

我有另一种可能的解决方法，但它需要手动干预。之所以失败，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（我在此处找到了它）。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
