两个错误

源地址重复

W: Target CNF (multiverse/cnf/Commands-all) is configured multiple times in /etc/apt/sources.list:50 and /etc/apt/sources.list:60

从错误信息就可以看出来，是/etc/apt/sources.list中的50行与60行配置了重复的两个地址。

随便注释其中一个即可

版本号没有找到

Err:8 http://cn.archive.ubuntu.com/ubuntu groovy Release
404 Not Found [IP: 91.189.91.39 80]

从http://cn.archive.ubuntu.com/ubuntu地址可以看到，如下图：

请添加图片描述

其中并没有groovy的版本号，所以替换为其中的一个可以解决

但在替换成bionic的时候，出现
