在ubuntu上安装java8时出现错误16.04

Question

我试图在Ubuntu 16.04上安装java 8。 遵循的步骤是：

$ sudo add-apt-repository ppa:webupd8team/java 
$ sudo apt-get update 
$ sudo apt install oracle-java8-installer 

，同时运行sudo apt install oracle-java8-installer我得到了下面的错误。

dpkg: error processing package unattended-upgrades (--configure): 
subprocess installed post-installation script returned error exit status 127 
No apport report written because MaxReports is reached already

请教我如何克服这个错误在Ubuntu上，并建议安装oracle-java8的步骤。

Answer 1

打开终端 - >并执行以下步骤顺序：

sudo add-apt-repository ppa:openjdk-r/ppa 
sudo apt-get update 
sudo apt-get install openjdk-8-jdk 

最后键入：java -version。 这个命令会告诉你在Ubuntu中是否安装了jdk。
