我刚刚在 NetBeans 6.9 上安装了一个插件（Python）——在此期间我的 Ubuntu Natty 几乎冻结了；不幸的是，每当发生太多文件操作时它似乎就会这样做。
我现在发现 NetBeans 无法启动。

有什么想法可以修复此问题吗？
答案1
我不确定 Ubuntu 是否以软件包的形式提供 Netbeans 插件，但如果确实如此，并且您已以这种方式安装此插件，您可以清除 ( apt-get purge) 软件包并重新安装。
如果此方法无效，唯一合理的方法就是删除 Netbeans 数据文件夹（使其恢复到全新安装的状态）——这是我处理此类问题时习惯的方法。Netbeans 太复杂了，无法手动编辑其配置文件。
