从 Ubuntu 18.04 卸载 Oracle Java

Question

我按照此链接中描述的步骤安装了 Oracle Java。

But now I want to remove this version of Java as I am using OpenJDK for a project, how can I remove oracle java now from my Ubuntu 18.04 system?

Answer 1

首先，您删除链接：

sudo update-alternatives --remove "java" "/usr/lib/jvm/jdk[version]/bin/java"    
sudo update-alternatives --remove "javac" "/usr/lib/jvm/jdk[version]/bin/javac"    
sudo update-alternatives --remove "javaws" "/usr/lib/jvm/jdk[version]/bin/javaws"

然后，您可以删除 package：

sudo rm -r /usr/lib/jvm/jdk[version]
