Oracle JDK 7 is NOT installed.
dpkg: error while cleaning up:
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java7-installer

因此，显然它正在尝试获取错误的URL。我已经手动安装了Java，但是现在该软件包卡在了一半位置，每次我执行apt-get install任何操作时，都会再次出现该错误。

apt-get install -f显示“ 1未完全安装或卸下。” 包并失败，并出现相同的错误。我已经尝试过dpkg -P oracle-java7-installer，但是也失败了。

如何删除这个半安装的软件包？

Awww yeahh .. 通过以下方法找到这篇文章后sudo find /var/lib/dpkg -exec grep -l "oracle-java7-installer" {} \;，我终于能够删除：显示了一堆文件，我已经exit 0通过键入sudo gedit /var/lib/dpkg/info/oracle-java7-installer.prerm，保存的文件和关闭的gedit 将其添加到第一行。最终，在我回到命令行后，键入sudo dpkg -P oracle-java7-installer并成功了。
