Ubuntu：OpenJDK 8-无法找到软件包

我试图安装 openJDK 8，但是当我运行命令时

$ sudo apt-get install openjdk-8-jdk 
Reading package lists... Done

 information... Done 

E: Unable to locate package openjdk-8-jdk

我搜索了互联网，发现有人建议运行以下2个命令：

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

以下是我得到的结果：

$sudo add-apt-repository ppa:webupd8team/java
Oracle Java (JDK) Installer (automatically downloads and installs Oracle > JDK7 / JDK8 / JDK9). There are no actual Java files in this PPA.

谁知道我该怎么办？

您链接的 ppa 适用于 Oracle 的封闭式 JDK。您可以在此处查看 PPA 的内容 -https://launchpad.net/~webupd8team/+archive/ubuntu/java

您可以像这样安装

sudo apt-get install oracle-java8-installer

目前看来 14.04 中没有内置任何 OpenJDK 8 软件包。请使用您正在运行的 Ubuntu 版本更新您的问题。我假设您运行的是 14.04，因为 14.10 及更高版本有 8。

更新 ：你可以用这个 PPA 安装它 -https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa

sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-8-jdk
sudo update-alternatives --config java
sudo update-alternatives --config javac

或者，如果您不想为此使用 PPA，您可以升级到 14.10。它确实在存储库中有它。
