问题分析

报错是因为需要安装某个依赖库，但是在安装过程中找不到该依赖，原因位置。可尝试解决方法：

• 代理
• 修改软件源

问题修复

1）备份源文件：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

2）查看版本信息
如是Linux Mint等Ubuntu衍生版，执行：

cat /etc/upstream-release/lsb-release

如是Ubuntu直接执行：

lsb_release -c

确认当前系统代号（Codename）为：bionic。如是其他版本，请使用其他版本的软件源，其中：

Ubuntu 12.04 (LTS)代号为precise。Ubuntu 14.04 (LTS)代号为trusty。Ubuntu 15.04 代号为vivid。Ubuntu 15.10 代号为wily。Ubuntu 16.04 (LTS)代号为xenial。

3）修改sources.list：
修改/etc/apt/sources.list为以下内容：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

4）检查更新

sudo apt-get update

5）重新安装软件

sudo apt-get install XXX
