安装Ubuntu 为避免后期麻烦可以尽量将home设置为大容量磁盘;
- 修改IP地址
输入IP地址和inet类型；
auto enp3s0
iface enp3s0 inet static #设置接口enp3s0网络类型为静态；address 192.168.18.202 #配置IP地址，address约定俗成的写法
netmask 255.255.255.0 #子网掩码配置
修改DNS
sudo vi /etc/resolvconf/resolv.conf/base
nameserver 8.8.8.8
nameserver 202.96.209.133
- 添加apt源
$sudo vi /etc/apt/sources.list
$sudo apt-get upgrade
复制以下源添加到sources.list源，注释到地方可以不用在意，主要为快速更新，不影响其他。
