它说没有安装OracleJDK。但是我的系统中已经安装了OracleJDK8。检查以下内容：

请帮我解决这个问题。

Oracle下载过程发生了一些变化，Internet上几乎所有的安装脚本都无法正常工作。坐下来放松一下，这个问题昨天早上就开始了。

或者，您可以添加Oracles PPA并使用apt get从那里安装。按照下面的命令操作

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

javac -version

这个erorr看起来像ppa:webupd8team/java存储库问题。下载链接现在已更改，无法下载JDK。

Hi@apesa，感谢您的评论……但是

sudo apt get install oracle-java8-insaller

给出了与我在上面的问题中提到的完全相同的错误。我意识到了这一点。虽然我上周刚为DSE集群安装了5台Linux机器，并使用了PPA，但它运行良好。这一定是WebUPD8团队的问题。嗨@DoctorPangloss，谢谢你的评论，我想你是对的。。。Oracle下载过程目前存在一些问题。。。我尝试了

sudo-apt-get-upgrade

命令，它运行得很好，但最后我得到了相同的java错误

处理时遇到的错误：oracle-java8-installer E:Sub-process/usr/bin/dpkg返回了一个错误代码（1）
