好的，这是我在 sudo apt-get update 或任何 sudo apt-get 操作期间遇到的所有错误
离开前请阅读！（谢谢 ^^）
（写完文才想起补充一句：顺便说一下，我用的是ubuntu 13.04！）
我不知道如何创建 sploiler，所以代码或整个终端将在最后提供。我只会解释我的情况。所以我尝试使用 Ubuntu（因为我很绝望，我尝试了任何可用的发行版（debian））或只是使用 linux，最终我让 Ubuntu 工作，那真是一个辉煌的时刻！但辉煌的时刻很快就消失了，因为最实际的用途也逐渐消失，是的，我说的是命令Sudo apt-get或操作。
我的 Android 手机是三星 Galaxy s4，以下是一些规格：
Model : "APQ8064T"
Cores : "4"
Architecture : "Krait 300"
Revision : "r1p0"
Process : "28nm"
Clock Speed : "384 MHZ - 1.89 GHz" #Pretty much a fast phone!
GPU Vendor : "Qualcomm"
GPU Renderer : "Adreno (TM) 320 @ 450 MHz"
Scaling Governor : Currently set to "ondemand"
所以我的意思是手机可以轻松地同时运行 Android 和 Ubuntu。
现在，我按照以下教程进行操作：这里
我按照步骤操作，我使用了“vnc”方法，基本上是在 ADB SHELL 或 TERMINAL EMULATOR 上以文本模式运行 Ubuntu，并允许 vnc 连接到它。我几乎不使用它，因为连接速度很慢，但它无论如何都坏了。您需要一个 .img 文件才能使用它。它使用 busybox 来安装循环设备或类似的东西，就像魔术一样，它运行完美！... 或者我是这么想的，无论如何，从我所看到的来看，它使用 armhf 运行，我的手机正在使用
Kernel Architecture : "armv7l"
所以我猜这意味着它使用的是什么架构。它确实有点过热（47c），但它只使用两个内核，处于中高使用率（分别为 918 MHz 和 1350！）
下面是部分文本，我已经尝试编辑 sources.list 但没有成功，我删除了“port.ubuntu”，将其改为“release.ubuntu”并且将“old-release.ubuntu”也改为，但似乎没有任何作用。
现在这些是 404 错误：
root@jflte:/ # sh /sdcard/ubuntu.sh
Making mount points and mounting to them...
Connecting to /sdcard...
Putting in some settings...
net.ipv4.ip_forward = 1
ubuntu is configured with SSH and VNC servers that can be accessed from the IP:
(You will see an error about wlan0 if your WiFi is disabled. Safe to ignore.)
----------------- OKAY, starting Ubuntu! -----------------
Start VNC server? (y/n)
y
Start SSH server? (y/n)
y
Now enter the screen size you want in pixels (e.g. 800x480), followed by [ENTER]:
1920x1080
New 'X' desktop is localhost:0
Starting applications specified in /home/ubuntu/.vnc/xstartup
Log file is /home/ubuntu/.vnc/localhost:0.log
If you see the message 'New 'X' Desktop is localhost:0' then you are ready to VNC into your ubuntu OS..
If connection from a different machine on the same network as the android device use the address below:
192.168.0.87
If using androidVNC, change the 'Color Format' setting to 24-bit colour, and once you've VNC'd in, change the 'input mode' to touchpad (in settings)
* Starting OpenBSD Secure Shell server sshd [ OK ]
Save settings as defaults? (y/n) (You can always change it later in the app)
n
To shut down the Linux environment, just enter 'exit' at this terminal - and WAIT for all shutdown routines to finish!

所以这是 sources.list 文件，请帮忙！我迫不及待地想让它工作 :) 我已经走了这么远了...
答案1
无论如何，经过深入挖掘后我找到了解决办法......
我找到了这个网站EOL升级
这对我有帮助。我刚刚做了，sudo apt-get update只收到一个 404，因为我添加了一个可选源
这是我的来源列表
deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ raring-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ raring-security main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ raring-backports main restricted universe multivers
最后一个将被删除。升级仍在进行中，正在安装...
对于收到此信息的人，只需添加 sources.list 并删除最后一行即可获得
deb http://old-releases.ubuntu.com/ubuntu/ raring main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ raring-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ raring-security main restricted universe multiverse
更新完成。正在安装 Java。
所以我现在就结束这篇文章了。谢谢你，muru，因为你鼓励我更深入地挖掘。:D
