我今天花了很多时间尝试在我的crunchbang发行版上安装java 7。我最初安装了OpenJDK但遇到了mumble服务器安装问题。现在（某种程度上）排序，但现在我没有java 7或OpenJDK。我的java版本是：
matt@crunchbang:~$ java -version
java version "1.5.0"
gij (GNU libgcj) version 4.7.2

尝试安装java 7时
（sudo apt-get install Oracle-java7-installer）我最终得到的错误如下：
sha256sum mismatch jdk-7u7-linux-x64.tar.gz
Oracle JDK 7 is NOT installed.
dpkg: error processing oracle-java7-installer (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

我在我的Chromebook上运行crunchbang wheezy并遇到了完全相同的问题。
这为我解决了这个问题：
我有一个类似的问题，我发现对我有用的东西 进入/ var / lib / dpkg / info并删除具有该名称的所有内容 您可能还需要进入/ var / cache / apt / archives并执行相同的操作 事情。我对linux很新，所以如果这打破了什么我很抱歉。 我还没有遇到任何导致这种问题的问题。
警告：
您正在删除安装前和安装后脚本。这很容易 意味着包装不能正确安装，而且不会 如果您选择卸载它，请正确删除。这是错误的事情 要做。
但是，我找不到任何其他解决方案。当然，我有点急于解决这个问题，所以我并没有花太多时间寻找替代解决方案。
