如何彻底删除安装不正确的oracle jdk？

Question

我最近在 Ubuntu 12.04 beta 上从 webupd8ppa 安装了一个 oracle jdk，但显然它没有成功，现在它在我每次更新或安装时都给我错误，即使在从我的来源停用 ppa 之后也是如此。

这是我尝试从 USC 卸载时得到的结果：

我也尝试从突触中“完全删除”，但它也不起作用。

提前谢谢你的帮助！

我在 Ubuntu 11.10 上遇到了同样的问题，尝试了所有相同的解决方案，但没有一个对我有用。我在另一个讨论板上找到了这个，它似乎对我有用：

如果你想删除oracle-jdk7-installer，你可以简单地去/var/lib/dpkg/info/加载需要一些时间，并删除所有以oracle-java7*****开头的文件~ 6files，然后转到 Synaptic 并简单地找到相同的 oracle-jdk，然后单击删除/完全删除。

这是我找到它的地方：http : //ubuntuforums.org/showthread.php?p=11821814

祝你好运！

编辑：以下是轻松执行此操作的 3 个步骤：

打开终端（ctrl + alt + T）并连续输入这两个命令：

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“应用”。

编辑：对于那些没有安装突触的人，在你 rm oracle 安装程序文件之后，只需执行以下操作：

sudo apt-get purge oracle-java7-installer

你应该很好。

编辑：也适用于 ubuntu 12.04 LTS
