我有一个系统，距离大约 3000 公里，所以我无法访问它。该机器运行的是 ubuntu 13.04（是的，它早就过了 EOL），python 模块完全乱了。当我尝试使用 do-release-upgrade 将其升级到 13.10，然后升级到 14.04（如所解释的那样这里）我收到此错误消息：
Traceback (most recent call last):
File "/usr/bin/do-release-upgrade", line 8, in <module>
from DistUpgrade.DistUpgradeVersion import VERSION
ImportError: No module named DistUpgrade.DistUpgradeVersion
甚至 UFW 也停止工作。它显示以下错误：
Traceback (most recent call last):
File "/usr/sbin/ufw", line 26, in <module>
import ufw.frontend
ImportError: No module named ufw.frontend
所以我想我可以重新安装 python，然后生活就好了。尝试重新安装 python 根本不起作用，所以我想也许我可以卸载 python 并重新安装它，这也是一个非常愚蠢的举动！现在我的 python 包被报告为清除，尝试使用 dpkg 或 apt-get 执行任何操作都会引发一百万个错误然后退出，并且几乎所有工具都不起作用！
我不介意升级或安装全新的 Ubuntu（我认为无论如何我都必须这样做），但我找不到任何线索如何通过网络做到这一点？这可能吗？

例如，当我尝试运行sudo dpkg --configure -a修复安装程序的问题时，我得到如下输出：

好吧，我最终基于 Ubuntu 13.04 创建了一个 AWS 实例，然后将所有 Python 包从 EC2 移到我的服务器。这并没有解决 apt-get 和 dpkg 的问题，但它让我可以运行其他基于 Python 的命令（例如 ufw 和 do-release-upgrade）。
然后我使用 do-release-upgrade 切换到 Saucy，然后是 Trusty。升级过程中出现了一些错误，但总体来说成功更新到了 14.04。
更新完成后，我再次运行apt-get install -f，dpkg --configure -a这次错误少了很多，但仍然失败了。我一个接一个地修复了错误，再次从另一台运行 14.04 的服务器借用损坏的软件包。
最后它迁移到 14.04 并且所有软件包问题也得到修复。
