Ubuntu 20.04换阿里源的方法
<p>注意，这篇文章其实不是简单的教你怎么换成20.04的源，而是教你一种基于20.04的方法来换源。<br>
笔者在写这篇文章的时候，20.04 还没有release出来正式版，但是已经可以在仓库里看到有源存在了，故写下这篇文章。</p>
<p>
请注意：Ubuntu 20.04 已于4月23日发布正式版本。<br>
请注意：发现有些软件比如ckermit，仓库里还没有，升级及换源自行斟酌。</p>
<p>
<strong>1 备份原来的源</strong></p>

要知道当前系统的代号，可以用以下命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_853010">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">lsb_release -a</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>

<img style="max-width:100%!important;height:auto!important;"title="Ubuntu 20.04换阿里源的方法" alt="Ubuntu 20.04换阿里源的方法" src="https://zhuji.jb51.net/uploads/img/202305/ea8288e664f78803389046df6f0ff60b.jpg"></p>
<p>
<strong>3 到阿里源看下这个源存在不存在</strong></p>
<p>
http://archive.ubuntu.com/ubuntu/dists/</p>
<p>

<p>
可以看到，现在已经有了ubuntu 20.04(代号focal)的源。</p>
