我有一個大約3000公里外的系統，所以我無法訪問它。這台機器運行的是 ubuntu 13.04（是的，它很久以前就已經 EOL），而 python 模組完全混亂。當我嘗試使用 do-release-upgrade 將其升級到 13.10，然後升級到 14.04 時（如所解釋的這裡）我收到此錯誤訊息：
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
就連 UFW 也停止運作了。它顯示了這個錯誤：
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裝python，生活就美好了。嘗試重新安裝 python 根本不起作用，所以我想也許我可以卸載 python 並重新安裝它，結果這也是一個非常愚蠢的舉動！現在我的 python 套件被報告為 purge，嘗試使用 dpkg 或 apt-get 執行任何操作都會拋出一百萬個錯誤，然後退出，幾乎所有工具都不起作用！
我不介意升級或安裝新的 ubuntu 副本（我認為我無論如何都必須這樣做），但我找不到任何線索如何透過網路執行此操作？有可能嗎？

例如，當我嘗試運行sudo dpkg --configure -a來修復安裝程式的問題時，我得到以下輸出：

好吧，我最終創建了一個基於 Ubuntu 13.04 的 AWS 實例，然後將所有 python 套件從 EC2 移至我的伺服器。這並沒有解決 apt-get 和 dpkg 的問題，但它讓我可以執行其他基於 python 的命令（例如 ufw 和 do-release-upgrade）。
然後我使用 do-release-upgrade 切換到 Saucy，然後切換到 Trusty。升級過程中出現了一些錯誤，但整體來說還是成功更新到了14.04。
更新完成後，我再次運行apt-get install -f，dpkg --configure -a這次錯誤少了很多，但仍然失敗。我再次透過從另一台運行 14.04 的伺服器借用損壞的軟體包來修復錯誤。
最後它遷移到 14.04，所有軟體包問題也都解決了。
