我在 Dell Inspiron 15-5547、AMD Radeon HD R7 M265 上使用带有 HWE 堆栈（内核 3.16）的 Ubuntu 14.04。
我一直在尝试安装专有驱动程序 fglrx 驱动程序，以便能够在显卡之间切换。经过一番尝试，我发现了这一点 这bug。没有仔细考虑，我按照评论 24 的建议运行
sudo apt-get install xserver-xorg-core
安装未完成，但返回

现在，我想撤销该更改。我尝试了、、、，sudo apt-get remove xserver-xorg-core但得到的结果是：sudo apt-get -f installsudo apt-get autoremovesudo apt-get cleansudo apt-get autoclean

You might want to run 'apt-get -f install' to correct these.

sudo apt update 或 sudo apt-get update 正常工作。

ls /etc/apt/sources.list.d 但请注意，这些大多已被禁用，应该不是问题。

答案1
正如你所说，这太乱了，这一定是由于你的存储库和 PPA 源存在问题
我建议先清理一下烂摊子：从
sudo apt-get install gksu
sudo apt-get install gedit
然后gksudo gedit /etc/apt/sources.list
在那里，在打开的文件中，用在那里生成的适当的 sources.list 替换所有内容：http://repogen.simplylinux.ch/（选中全部但不要选中“建议”。）
保存文件时关闭它。然后
sudo apt-get autoclean
sudo apt-get clean
查看 ：ls /etc/apt/sources.list.d
还摆脱了精确的戴尔 PPA。
然后尝试
sudo apt update
sudo apt-get install -f
sudo apt full-upgrade
如果仍然被阻止，您可能必须先摆脱阻止包：
sudo dpkg -r --force-remove-reinstreq 'TheBlockingPackage'
