Debian Jessie 上的預設 sources.list（無法滿足的依賴項）

作業系統和硬體：聯想 G50-45 上的 Debian Jessie x64 肉桂

我剛剛在朋友的筆記型電腦上安裝了一個新的 Debian Jessie (Debian 8.7.1 x86_64 Cinnamon)，我需要升級核心和一些東西，我在 #debian IRC 與這 3 人聊天中被引導到這些步驟為了使 WiFi 正常工作的軟體包：

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

我現在遇到的問題是我無法安裝任何東西。

我嘗試安裝的每個程序，甚至像 DosBox 這樣簡單的程序，都會給我關於無法滿足的依賴關係的錯誤。

這是什麼原因以及如何補救？

造成這種情況的原因可能是您的軟體源內容不正確。補救措施：

1. 使用您最喜歡的編輯器編輯您的來源，nano如果不確定，請使用：

sudo nano /etc/apt/sources.list

2. 註釋掉（用#）所有 CD 行。
3. 確保除了 CD 之外還有其他東西；
4. 如果沒有其他內容，您可以複製粘貼以下完整列表：

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. 更新記憶體：

sudo apt-get update

6. 安裝你需要的任何東西；）

考慮一些事情可能是明智的，即在這個答案中，這兩個：

• 如果不需要軟體源，可以省略deb-src行。這意味著，如果您目前不需要自己編譯任何軟體，則不需要這些行，但是因為它們不會造成傷害…
• 如果您打算只使用純 GNU 自由軟體，您可以non-free從所有行中省略，如果不確定，或者對 Linux 不熟悉，您可能會想要一些non-free軟體，但是…
