Debian Jessie 上的默认sources.list（无法满足的依赖项）

Debian Jessie 上的默认sources.list（无法满足的依赖项）

操作系统和硬件：Lenovo G50-45 上的 Debian Jessie x64 cinnamon

我刚刚在朋友的笔记本电脑上安装了新的 Debian Jessie (Debian 8.7.1 x86_64 Cinnamon)，我需要升级内核和一些东西，#debian IRC 聊天中的一个人向我指示了这些步骤，这 3 个软件包以使 WiFi 正常工作：

linux-image-4.8.0-0.bpo.2-amd64_4.8.15-2~bpo8+2_amd64.deb
linux-base_4.3~bpo8+1_all.deb
firmwqare-atheros_20161130-2~bpo8+1_all.deb

我现在遇到的问题是无法安装任何东西。

我尝试安装的每个程序，甚至像 DosBox 这样简单的程序，都会给我带来有关无法满足的依赖项的错误。

这是什么原因以及如何补救？

造成这种情况的原因可能是您的软件源内容不正确。要补救它：

  1. 使用您最喜欢的编辑器编辑您的源代码，nano如果不确定，请使用：

    sudo nano /etc/apt/sources.list

  2. 注释掉（用#）所有 CD 行。

  3. 确保有某物除了 CD 之外；

  4. 如果没有其他问题，您可以复制粘贴以下完整列表：

    deb http://httpredir.debian.org/debian jessie main contrib non-free
deb-src http://httpredir.debian.org/debian jessie main contrib non-free

deb http://httpredir.debian.org/debian jessie-updates main contrib non-free
deb-src http://httpredir.debian.org/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

  5. 更新缓存：

    sudo apt-get update

  6. 安装你需要的任何东西;)

考虑一些事情可能是明智的，即在这个答案中，考虑这两件事：

  • 如果不需要软件源，则可以省略deb-src这些行。这意味着，如果您当前不需要自己编译任何软件，则不需要这些行，但因为它们不会造成伤害......

  • 如果您打算只使用纯 GNU 自由软件，则可以non-free从所有行中省略，如果不确定，或者对 Linux 不熟悉，您可能会想要一些non-free软件，但是......
