Ubuntu类似下面的安装包依赖问题：
      libc6-dev : 依赖: libc6 (= 2.23-0ubuntu11) 但是 2.27-3ubuntu1 正要被安装

      build-essential: 依赖: g++ (>= 4:4.3.1) 但是它将不会被安装

1.将原来的源文件备份

cd /etc/apt
mv sources.list sources.list.back

2.更换为阿里源

vim sources.list

将下面的阿里源复制粘贴进去

阿里源：

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

3.更新软件

apt-get update
apt-get upgrade
