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

所以显然它试图获取一个错误的 URL。我已经手动安装了 Java，但是现在这个包被卡在了一半的安装中，每次我做apt-get install任何事情时，错误都会再次出现。

apt-get install -f显示“1 未完全安装或删除”。打包并失败并出现相同的错误。我试过了dpkg -P oracle-java7-installer，但它也失败了。

如何删除这个半安装的包？

Answer 1

Awww 是啊.. 在找到这篇文章后sudo find /var/lib/dpkg -exec grep -l "oracle-java7-installer" {} \;，我终于能够通过以下方式删除：显示了一堆文件，我已经exit 0通过输入添加到第一行sudo gedit /var/lib/dpkg/info/oracle-java7-installer.prerm，保存文件并关闭 gedit。最后，在我回到命令行后，输入sudo dpkg -P oracle-java7-installer并且它起作用了。
