ubuntu更换源

<p>&nbsp;</p>
<p>1、备份一下原来的文件</p>
<p>cp /etc/apt/sources.list&nbsp; /etc/apt/sources.list.bak</p>
<p>2、打开source.list文件</p>
<p>vi&nbsp;etc/apt/sources.list</p>
<p>ggVG全部选择&nbsp; &nbsp;d删除</p>
<p>或者直接dG全部删除</p>
<p>3、找到计划使用的源，以aliyun为例，从以下链接内找到对应系统版本的源，拷贝至sources.list，保存即可。</p>
<p>https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.3e221b11BS9NLJ</p>
<p>我的是ubuntu20.1的版本，用的以下配置：</p>
<p>可以用&nbsp; &nbsp;lsb_release -a 查看一下当前的版本。正常情况也得看对应的codename，如18.04对应的是bionic，20.04对应的是focal。20.1当前是groovy，但因为aliyun尚未提供最新的版本，所以直接用20.04的就行。</p>
