在虚拟机新建一个Ubuntu18.04.1-live-server-amd64当做服务器

在安装软件时报错：

slave@slave:~$ sudo -s  
\[sudo\] password for slave:

root@slave:~\# apt install redis-server  
Reading package lists... Done  
Building dependency tree   
Reading state information... Done  
python3 is already the newest version (3.6.5-3ubuntu1).  
0 upgraded, 0 newly installed, 0 to remove and 27 not upgraded.

root@slave:~\# apt-get -f install  
Reading package lists... Done

从报错信息上看可能存在一些依赖问题或者软件源出了问题，修复一下破损的依赖关系还是一样的错误信息，此时应该更换Ubuntu的源。

**如何更换Ubuntu的源**

①进入root模式

②进入ubuntu源的目录

③备份sources.list

<table> 
 <tbody> 
  <tr> 
   <td> <p><code>cp sources.</code><code>list</code>&nbsp;<code>sources.</code><code>list</code><code>.bak</code></p> </td> 
  </tr> 
 </tbody> 
</table>

④修改sources.list

删除sources.list中的内容，把阿里云的源复制进source.list中

<table> 
 <tbody> 
  <tr> 
   <td> <p><code>vi sources.</code><code>list</code></p> </td> 
  </tr> 
 </tbody> 
</table>

再次安装软件就不会报错了
