Ubuntu22.04 安装经验

*以下操作均在VMware中进行*

1. 断网安装，以防中途更新导致安装缓慢

2 .最好不要在安装的时候填写代理地址，可能会照成后续代理源替换不成功

3. 断网需要主动选择DHCP网络自动获取，如果忘记选择采用以下是处理方式：

sudo dhclient ens33
ps:ens33是你的网卡名称，通过ip addr 可获得网卡列表
  
 -------启动自动DHCP-------
  sudo nano /etc/netplan/50-cloud-init.yaml
  network:
  		ethernets: 
        ens33: 
          dhcp4: true
          dhcp-identifier: mac
        version: 2
 --------------
配置：dhcp-identifier可以解决ip重复的问题（特别是VM克隆系统）
