从webup8team ppa安装oracle-java8-installer时出错

有谁知道如何解决这一问题？

首先，我做了：

sudo add-apt-repository ppa:webupd8team/java  

然后我做了：

sudo apt-get update

接着：

$ sudo apt-get install oracle-java8-installer

以下可能有效，它将删除任何部分：

sudo rm /var/cache/oracle-jdk8-installer/jdk-*

然后使用以下命令完成安装：

sudo apt-get install -f
sudo dpkg --configure -a

在sudo apt-get upgrade公司代理后面发生此错误。要修复，我编辑/etc/apt/apt.conf并添加了以下几行：

Acquire::http::Proxy "http://[<proxyUserName>:<proxyPass>@]<proxyUrl>:<proxyPort>"; Acquire::https::Proxy "http://[<proxyUserName>:<proxyPass>@]<proxyUrl>:<proxyPort>";

哪里

• [<proxyUserName>:<proxyPass>@] 是您的可选代理身份验证（如果不进行身份验证，则不包括此身份）

• <proxyUserName> 是您的代理用户名

• <proxyPass> 是您的代理密码

• <proxyUrl> 是您的代理网址

• <proxyPort> 是您的代理端口

oracle tarball是通过https下载的，因此如果您位于代理后面，则apt需要一个https代理来执行它。

编辑后，保存文件，然后打开一个新终端。sudo apt-get update并根据需要安装。

当我的Ubuntu系统无法从oracle服务器下载文件（file jdk-8u111-linux-x64.tar.gz）时，我遇到了类似的问题。因此，我不得不从oracle站点（http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html）下载该文件，然后/var/cache/oracle-jdk8-installer/手动将其复制到文件夹中。这解决了问题，并且oracle-java8-installer能够完成安装。

我有一个同样的问题，我发现这是对我有用的解决方案：

sudo rm /var/lib/dpkg/info/oracle-java8-installer.postinst -f
sudo dpkg --configure oracle-java8-installer
