Ubuntu安裝后默認(rèn)的官方源是美國(guó)的服務(wù)器，但是美國(guó)服務(wù)器在國(guó)內(nèi)安裝軟件等會(huì)有較大的限制。所以我們需要將默認(rèn)的源切換為國(guó)內(nèi)源。一般來(lái)說(shuō)，常用的國(guó)內(nèi)源有阿里源（這是中國(guó)官方源）、網(wǎng)易源和搜狐源等等。除此之外，還有高校源，比如清華、中科大以及浙大等等。如果是在校學(xué)生，那么換成自己學(xué)校內(nèi)部的源，更新和安裝軟件的速度會(huì)很快。如果是非校園網(wǎng)絡(luò)，那么最推薦的就是阿里源。不同版本的Ubuntu系統(tǒng)的源列表不相同，在這里我只列舉Ubuntu 16.04系統(tǒng)的源列表。
1. 更換源的兩種方式
（1）打開(kāi)系統(tǒng)設(shè)置選擇，software&updates，如下：
然后在跳出來(lái)的框中點(diǎn)擊選擇”Download from：“選項(xiàng)
再點(diǎn)擊other選項(xiàng)會(huì)出現(xiàn)一個(gè)choose a download server框并選擇China，里面有很多國(guó)內(nèi)服務(wù)器可選擇。
（2）在sources.list文件中手動(dòng)更改源，即將對(duì)應(yīng)源列表中的代碼復(fù)制到sources.list文件中，過(guò)程如下：
<1> 打開(kāi)終端，通過(guò)cd指令進(jìn)入sources.list文件所在目錄。
$ cd /etc/apt
<2> 將原sources.list文件拷貝做備份，可以進(jìn)入/etc/apt目錄下看到有一個(gè)sources.list.bak文件。
$ sudo cp sources.list sources.list.bak
<3> 通過(guò)gedit指令對(duì)sources.list進(jìn)行編輯（也可以用vim指令），并將sources.list文件中的內(nèi)容全選刪除，再把對(duì)應(yīng)的源列表的內(nèi)容復(fù)制到文件中。
$ sudo gedit sources.list
或 執(zhí)行
$ sudo vi sources.list 進(jìn)入 sources.list后 按 ggdG 快捷vi操作刪除原文件內(nèi)容
<4>訪問(wèn)源列表里的網(wǎng)址，并讀取軟件列表，然后更新保存在本地電腦，換源結(jié)束。
$ sudo apt-get update
國(guó)內(nèi)的源地址
