我浏览了一些帖子，但没有找到解决方案，如果有重复的话，请原谅。
在搞乱了某些软件包的安装（见下文）之后，尝试安装任何东西都会产生以下结果：
$ sudo apt-get install sl Reading package lists... Done

The following packages were automatically installed and are no longer required:
linux-headers-4.2.0-34 linux-headers-4.2.0-34-generic linux-image-4.2.0-34-generic linux-image-extra-4.2.0-34-generic
Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
jdk1.8.0-77
The following NEW packages will be installed:

什么破坏了一切：我尝试在 Ubuntu Gnome 机器上安装 jdk8。我做了以下操作：
- 从以下位置下载相关的 .rpmOracle 的网站，用于
alien --scripts将其转换为 .deb，然后使用进行安装dpkg -i。这不起作用（它花了一些时间进行安装，然后抱怨一些安装脚本。不完全确定确切的消息是什么）。 - 已关注本指南。当到达该
apt-get install部分时，安装最终失败。
我试过了apt-get autoremove和apt-get autoclean，还有dpkg -P jdk1.8.0-77。
值得一提的是，在安装完其中一个后，会在与 .rpm 相同的文件夹中创建一个名为 jdk1.8.0-77/ 的文件夹，该文件夹带有锁图标（在文件浏览器中）。我删除了该文件夹，因为我以为我下载了它。
编辑：apt-get install -f收益

编辑2：这帖子似乎非常相关。我尝试按照那里给出的建议操作（touch但/usr/sbin/alternatives脚本现在在调用时失败find）
编辑 3：重新启动（以及伪随机组合apt-get autoremove和dpkg -P加上对脚本的一些干预似乎已经解决了这个问题。
