在Ubuntu 15.10上安装Java 8时出错

我使用以下命令在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，我遇到了一个问题。

这是问题所在：
