uninstall - 如何完全删除未正确安装的Oracle JDK？

问题描述

我最近在Ubuntu 12.04 beta上从webupd8ppa安装了一个oracle jdk，但显然无法解决问题，现在，即使从源中停用了ppa，它在每次执行更新或安装时都给我错误。

这是我尝试从USC卸载时得到的：

我也从突触中尝试了”remove completely”，但它也不起作用。

提前谢谢你的帮助！

最佳方案

我在Ubuntu 11.10上遇到了相同的问题，尝试了所有相同的解决方案，但都不对我有用。我在另一个讨论板上找到了它，似乎对我有用：

If you want to remove oracle-jdk7-installer, you can simply go to /var/lib/dpkg/info/ It takes some time to load, and delete all files which starts with oracle-java7***** there was ~6files, then go to Synaptic and simply locate same oracle-jdk and click remove/completly remove.

我在这里找到它：http://ubuntuforums.org/showthread.php?p=11821814

祝好运！

编辑：这是轻松执行此操作的3个步骤：

打开一个终端(ctrl + alt + T)并依次键入以下两个命令：

cd /var/lib/dpkg/info/
sudo rm oracle-java7-installer*

打开突触，搜索”oracle-java7-installer”，将其标记为完全删除，然后单击”apply”。

编辑：对于那些没有安装突触的服务器，在管理oracle安装程序文件后，只需执行以下操作：

sudo apt-get purge oracle-java7-installer

而且你应该很好。

编辑：也在ubuntu 12.04 LTS上工作

次佳方案

再次添加webupd8 ppa

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

打开终端并输入：

  sudo apt-get update
  sudo apt-get install -f

然后使用ppa purge清除ppa

sudo apt-get install ppa-purge
sudo ppa-purge ppa:webupd8team/java
