我通过从 java.com (1.8.0-71) 下载 RPM 文件来安装 java并使用外星人生成 .deb 我安装的文件。它失败了，我不能再删除它了。

如果我尝试使用 apt-get ，我总是会收到一条提示，我应该重新安装软件包(如果它很容易的话):

LC_ALL=C sudo dpkg --purge --force-all jre1.8.0-71
dpkg: warning: overriding problem because --force enabled:

第二行说它处于非常糟糕的不一致状态。它尝试访问尚未创建的文件夹，因此在我尝试的所有操作中都失败了。我是否可以删除 dpkg 中的安装条目，就好像我从未安装过一样？我不再关心它是否 super 干净，我只想能够再次使用 apt-get。

您不应该那样安装 Java。

首先，捕获 tar.gz 从这里:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

然后执行以下步骤:

sudo apt-get purge openjdk-\*

sudo mkdir -p /usr/local/java

cd Downloads/

sudo mv jdk-8u72-linux-x64.tar.gz /usr/local/java/

cd /usr/local/java/

sudo tar xvzf jdk-8u72-linux-x64.tar.gz 

sudo rm jdk-8u72-linux-x64.tar.gz

然后打开您的个人资料，并在末尾复制以下行:

须藤 gedit/etc/profile

JAVA_HOME=/usr/local/java/jdk1.8.0_72
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export PATH

最后执行以下步骤:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.8.0_72/bin/java" 1

sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.8.0_72/bin/javac" 1

sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.8.0_72/bin/javaws" 1

sudo update-alternatives --set java /usr/local/java/jdk1.8.0_72/bin/java

sudo update-alternatives --set javac /usr/local/java/jdk1.8.0_72/bin/javac

sudo update-alternatives --set javaws /usr/local/java/jdk1.8.0_72/bin/javaws

请注意，“cd Downloads/”部分在您的情况下可能会有所不同，而且，您可以将它放在您想要的任何位置，而不仅仅是/usr/local/java/- 只需确保在任何地方都使用相同的路径。
