Ubuntu更新到11.04，卻無法安裝vim

請教~
我將server由10.04升級到11.04
升級過程一切順利
重新開機完 要安裝vim卻無法升級，並出先底下訊息:
--------------------------------------------------------------
~$ sudo apt-get install vim
正在讀取套件清單... 完成
正在重建相依關係
正在讀取狀態資料... 完成
有些套件無法安裝。這可能意謂著您的要求難以解決，或是若您使用的是
unstable 發行版，可能有些必要的套件尚未建立，或是被移出 Incoming 了。
以下的資訊或許有助於解決當前的情況：

下列的套件有未滿足的相依關係：
vim : 相依關係: vim-common (= 2:7.2.330-1ubuntu3) 但 2:7.3.035+hg~8fdc12103333-1ubuntu7 卻將被安裝
       相依關係: libpython2.6 (>= 2.6) 但它卻將不會被安裝
E: 損毀的套件
--------------------------------------------------------------
我該如何安裝vim呢?謝謝!

當初Server版會用10.04是因為
它的套件維護為五年
而11.04也不過維護二年
所以沒升級必要
呵....

報告~是的
真的是沒升級沒事
升級完一堆事
白忙一場啦...
請問可以"降級"回來嗎?

呵...
有請村老回答
村老請了....

是喔....慘!

相依關係: libpython2.6 (>= 2.6) 但它卻將不會被安裝
11.04應該是  libpython2.7

是否套件庫有問題或不正確
查一下/etc/apt 內的檔案看看
例如 /etc/apt/sources.list 這個檔

感謝亮哥~
這部份是真的是 /etc/apt/sources.list的問題
因為那時我的sources.list還是使用10.04版的
於是到 Ubuntu 正體中文站找到11.04的sources.list套用就OK了
至於為什麼版本不同，sources.list的設定也不一樣
這部分我並不是很清楚!
底下列出11.04的sources.list，提供有需要的夥伴:
