</div>
<p>原因是由于Debian官方将Debian10(Debian buster)软件源由默认站点deb.debian.org移至存档站点archive.debian.org，基于官方软件源的镜像站同步了这一修改， 导致20250723之前的Debian10镜像在运行apt update命令时会报错： buster Release 404 Not Found 。 </p>
<p>解决方法是：<strong>切换至Debian归档仓库（维持Buster）</strong></p>
<p>适用场景：需保留Debian 10环境，不升级系统。</p>
<p><strong>步骤：</strong></p>
<p>1、修改镜像源为官方归档地址：</p>
<div class="cnblogs_code">
<pre>deb https://archive.debian.org/debian buster main contrib non-free
deb-src https://archive.debian.org/debian buster main contrib non-free
deb https://archive.debian.org/debian-security buster/updates main contrib non-free
deb-src https://archive.debian.org/debian-security buster/updates main contrib non-free
deb https://archive.debian.org/debian buster-updates main contrib non-free
deb-src https://archive.debian.org/debian buster-updates main contrib non-free</pre>
</div>
<p>或者阿里云镜像软件源</p>
<div class="cnblogs_code">
<pre>deb https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian buster main contrib non-free</span>
deb-src https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian buster main contrib non-free</span>
deb https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian-security buster/updates main contrib non-free</span>
deb-src https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian-security buster/updates main contrib non-free</span>
deb https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian buster-updates main contrib non-free</span>
deb-src https:<span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">mirrors.aliyun.com/debian-archive/debian buster-updates main contrib non-free</span></pre>
</div>
<p> </p>
<p>2、更新并安装软件：</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 255, 1)">sudo</span><span style="color: rgba(0, 0, 0, 1)"> apt update
</span><span style="color: rgba(0, 0, 255, 1)">sudo</span> apt <span style="color: rgba(0, 0, 255, 1)">install</span> <软件包名> --allow-unauthenticated# 忽略证书警告</pre>
</div>
