如果您使用以下方式安装 JavaWebupd8脚本，然后要卸载 Java，请执行以下操作：

sudo apt-get remove --purge oracle-java8-installer

如果您从 Ubuntu 存储库安装了 Java，则可以通过键入以下命令将其删除：

sudo apt-get remove --purge openjdk-*

答案2

要卸载现有的 Java，可以执行以下命令：

sudo apt-get remove openjdk-8-jre
sudo apt-get remove openjdk-8-jre-lib

要再次安装 Java V8，

sudo apt-get install openjdk-8-jdk

答案3

/usr/sbin/alternatives: No such file or directory可以通过创建一个空文件来解决此错误。
