• ~/software 目录下安装离线下载的安装包
• /opt 目录下，安装个人下载的软件包

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

$ sudo cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime
