1.復(fù)制源文件備份，以防萬(wàn)一

我們要修改的文件是sources.list，它在目錄/etc/apt/下，sources.list是包管理工具apt所用的記錄軟件包倉(cāng)庫(kù)位置的配置文件，同樣類型的還有位于 同目錄下sources.list.d文件下的各種.list后綴的各文件。

命令如下：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2.編輯源列表文件

命令如下：

sudo vim /etc/apt/sources.list

3.查看新版本信息

其實(shí)Ubuntu18.04版之前的任一版更改apt源為國(guó)內(nèi)源方法早就有了，內(nèi)容大同小異，我們應(yīng)當(dāng)掌握其規(guī)律了，其實(shí)每一版內(nèi)容不同的地方就是版本號(hào)（或者官方一點(diǎn)的說(shuō)：系統(tǒng)代號(hào)），所以我們先了解下新版本的系統(tǒng)代號(hào)：

使用如下命令：

lsb_release -c

得到本系統(tǒng)的系統(tǒng)代號(hào)，如下圖所示：

我們可以看到新版本的Ubuntu系統(tǒng)代號(hào)為bionic 同樣的我們也可以得到之前任意版本的系統(tǒng)代號(hào):

• Ubuntu 12.04 (LTS)代號(hào)為precise。
• Ubuntu 14.04 (LTS)代號(hào)為trusty。
• Ubuntu 15.04 代號(hào)為vivid。
• Ubuntu 15.10 代號(hào)為wily。
• Ubuntu 16.04 (LTS)代號(hào)為xenial。

所以這也就解釋了為什么我們百度出來(lái)的那么多方案里面內(nèi)容不盡相同的原因，因?yàn)樗麄兏腶pt安裝源時(shí)用的系統(tǒng)不一樣。

4. 修改源

將原有的內(nèi)容注釋掉，添加以下內(nèi)容（或者你把里面內(nèi)容修改成下面的就可以，但是不能有除了以下內(nèi)容的有效內(nèi)容, 注意，下面給的幾個(gè)源，選一個(gè)就好）
