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

  1. Why is ‘ppa-purge’ not installed by default?

  4. Are PPA’s safe to add to my system and what are some “red flags” to watch out for?
