在 ubuntu 15.10 上安装 java 8 时出错

我使用以下命令在我的 ubuntu 服务器上安装 java 8：

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo update-java-alternatives -s java-8-oracle

但是在一台服务器上，当我输入 apt-get install oracle-java8-installer....并接受条款后，出现了问题...

问题如下：

以下命令详细说明如下 在 Ubuntu 16.04、Linux Mint 18 中安装 Oracle Java 8/9

简单来说，步骤如下：

  1. 添加 PPA。打开终端（Ctrl+Alt+T）并运行命令：

    sudo add-apt-repository ppa:webupd8team/java
