我刚刚升级了我的笔记本电脑（我买了它已经一周了，但用得不多），同时安装了 python 3.4。我遇到了一些未满足的依赖关系问题，如下所示：
当我使用代码时：
sudo apt-get install python 3.4
sparsh@sparsh-Inspiron-3558:~$ sudo apt-get install python 3.4

我不知道为什么它显示 NVIDIA 问题，我甚至没有 NVIDIA 显卡，我只有一张简单的显卡。
我不知道如何解决这些未满足的依赖关系问题，我想问几个问题：
1) 我刚买了这台笔记本电脑一个星期，从 14.04 升级到 16.04 时，总是出现依赖关系未满足的错误。因此，我无法升级它。我至少已经将笔记本电脑的设置更改为出厂设置四次了。
2）由于这个原因，我的笔记本电脑的工作状况也发生了变化，有点恶化了。
3）请告诉我如何使用 synaptic 包管理器或终端解决这些问题
4）戴尔提供的 ubuntu 14.04 版本是否错误？
请帮忙，这真的很棒
尝试该命令后，
sparsh@sparsh-Inspiron-3558:~$ sudo apt-get remove libcuda1-304 libcuda1-304-updates nvidia-304 nvidia-304-updates nvidia-libopencl1-304 nvidia-libopencl1-304-updates nvidia-opencl-icd-304 nvidia-opencl-icd-304-updates
它显示了以下输出

基本上我没有安装这些，我不知道为什么存在未满足的依赖关系问题？

有两种方法可以解决这个问题：困难的方法和简单的方法。
艰难之路
你没有在问题中输入正确的 Python Interpreter (v3.4) 包名称。打开终端并输入：
sudo apt-get install python3.4
在 Ubuntu 14.04 中，此命令将正确安装 python3.4 包。使用 Ubuntu 14.04 中的 Ubuntu 软件中心安装软件将避免发生此类错误。
如何处理所有 nvidia 软件包依赖项？您现在不需要 nvidia 软件包，即使您需要它们，您也可以稍后重新安装它们。同时，这些冲突的软件包会妨碍您。要删除它们，请输入：
sudo apt-get remove ibcuda1-304 libcuda1-304-updates nvidia-304 nvidia-304-updates nvidia-libopencl1-304 nvidia-libopencl1-304-updates nvidia-opencl-icd-304 nvidia-opencl-icd-304-updates
sudo reboot
简单的方法
Ubuntu 并非设计为尖端操作系统。它旨在成为人类的操作系统，其中所有功能都应该开箱即用。既然您刚刚购买了笔记本电脑，那么在您了解操作系统的工作原理并全新安装 Ubuntu 16.04 之前，您没有理由不放弃成为系统工程师的尝试。
