Ubuntu中文版預設選擇的是cn.archive.ubuntu.com作為更新源(如果喜歡英文介面的使用者那麼更新源預設是Ubuntu官網的)，在更新系統或者apt-get安裝一些軟體的時候速度會非常慢，大陸使用者最好是新增其他合適的源到源列表的前面。我覺得速度比較不錯的源是搜狐、網易和臺灣的源，教育網的推薦使用北理工的，貌似這個學校是教育網的骨幹節點。    不過很奇怪的是，中國ubuntu官方源(cn.archive.ubuntu.com)是搜狐維護的，和搜狐的映象mirrors.sohu.com是同一個，但是搜狐卻把這個源放在了山東網通這個二線機房，再加上具有中國特色的南北電信差異，直接導致很多南方使用者使用中國ubuntu官方源的時候也很慢。我剛到搜狐一週，使用搜狐的源更新飛快，所以很奇怪為啥搜狐沒有把這個源放在中心機房。

    更改過/etc/apt/sources.list之後一定要執行apt-get update進行更新，其他Linux發行版本一般都可以在上述映象找到各自的更新源。    不同的網路狀況連線以下源的速度不同, 建議在新增前手動驗證以下源的連線速度(ping下就行),選擇最快的源可以節省大批下載時間。

Ubuntu 下 apt-get 更新源推薦
     
                          Ubuntu中文版預設選擇的是cn.archive.ubuntu.com作為更新源(如果喜歡英文介面的使用者那麼更新源預設是Ubuntu官網的)，在更新系統或者apt-get安裝一些軟體的時候速度會非常慢，大陸使用者最好是新增其他合適的源到源列表的前面。我覺得

ubuntu的apt-get很好用，但有時會找不到軟體包，會報錯如下：
現在沒有可用的軟體包 openssh-server,但是它被其它的軟體包引用了.
這可能意味著這個缺失的軟體包可能已被廢棄,或者只能在勞動保險釋出源中找到.
E:軟體包openssh-server還沒有

Ubuntu配置任意版本的apt-get映象源
     
 
                

我們知道，迄今為止，Ubuntu已有多個發行版，如11.04、11.10，以至於現在最新的16.10。而我們平常通過apt-get來安裝軟體，如果OS版本不同，那麼映象源的配置就不同，否則就會出現找不到對應軟體、軟體版本不匹配等一系列奇怪的問題。這裡，我就講述一下如何配置
