ubuntu添加阿里源 失败
<p>环境 ubuntu 19.04</p><p>日期2020/04/18</p>
<p> </p>
<p>更新软件失败，以为是源的问题 ，所以尝试 修改 源为 国内阿里源</p>
<p>查看 系统版本</p>
<p>lsb_release -a<br>No LSB modules are available.<br>Distributor ID: Ubuntu<br>Description: Ubuntu 19.04<br>Release: 19.04<br>Codename: <span style="color: rgba(255, 0, 0, 1)">disco</span><br><br></p>
<p>其中的codename是这个版本的系统别名</p>
<p>查看阿里源</p>
<p>http://mirrors.aliyun.com/ubuntu/dists/</p>
<p>发现如下内容，以为支持，所以更换阿里源</p>
