Ubuntu本身的源使用的是国内的源，下载速度比较慢，不像CentOS一样yum安装的时候对镜像站点进项选择， 
所以选择了更换成国内的源。 
以下内容整合自网络

备份/etc/apt/sources.list文件
mv /etc/apt/sources.list /etc/apt/sourses.list.backup

新建/etc/apt/sources.list文件并添加以下内容

#163源

deb http://mirrors.163.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ bionic-backports main restricted universe multiverse

更改完成之后执行以下命令

# apt update
# apt upgrade
