【Linux】Ubuntu替换阿里源
<p>---------------------------------------------------------</p><p>参考文章：https://www.jianshu.com/p/97c35d569aa3</p>
<p>---------------------------------------------------------</p>
<p>因为Ubuntu自带的源服务器在国外，下载和更新软件的时候速度很慢，不稳定，所以需要将源更新为国内的源。国内的源比较多，常用的就是阿里的源。</p>
<p>1.备份原有源文件，方便在替换出问题时回滚</p>
<div class="cnblogs_code">
<pre>sudo cp /etc/apt/sources.list /etc/apt/source.list.bk</pre>
</div>
<p>2.更改sources.list文件</p>
<div class="cnblogs_code">
<pre>vim /etc/apt/sources.list</pre>
</div>
<p>替换里面的内容为</p>
<div class="cnblogs_Highlighter">
<pre class="brush:bash;gutter:true;"># 阿里源

<p>这里需要注意的是不同的ubuntu发行版本对应的源也是不一样的，主要的区别在版本号</p>
<p>Ubuntu 12.04 (LTS)代号为precise。</p>
<p>Ubuntu 14.04 (LTS)代号为trusty。</p>
<p>Ubuntu 15.04 代号为vivid。</p>
<p>Ubuntu 15.10 代号为wily。</p>
<p>Ubuntu 16.04 (LTS)代号为xenial。</p>
<p>Ubuntu 18.04 (LTS)代号为bionic。</p>
<p>Ubuntu 19.10 代号为eoan。</p>
<p>目前我的版本是18.04所以里面的版本号是bionic，如果是其他版本号直接替换里面的版本编号即可。</p>
<p>查看自己ubuntu的版本号：</p>
<div class="cnblogs_code">
<pre>lsb_release -c</pre>
</div>
<p>3.更新源</p>
<div class="cnblogs_code">
<pre>sudo apt update</pre>
</div>

<p>附：</p>
<p>刚安装Ubuntu时，系统只自带了vi,而没有vim</p>
<p>安装vim</p>
<div class="cnblogs_Highlighter">
<pre class="brush:Perl;gutter:true;">apt install vim
</pre>
</div>
<p> </p>
<p>vim全选删除</p>
<p>按esc进入视图模式，ggVG进行全选，d删除</p><br><br>
