Ubuntu 网络配置与阿里云源设置

1. 网络配置（Netplan 示例）

network: 
  version: 2 
  ethernets: 
    ens33: 
      addresses: 
        - 192.168.66.106/24 
      routes: 
        - to: default 
        via: 192.168.66.254 
      nameservers: 
        addresses: 
        - 8.8.8.8 
        - 114.114.114.114 
      dhcp4: false

2. Ubuntu 阿里云镜像源配置

将以下内容添加到 /etc/apt/sources.list 文件中，替换原有源即可：

deb https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse 
deb-src https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse  

deb https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse 
deb-src https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse  

deb https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse 
deb-src https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse  

# 以下为可选源，默认注释 
# deb https://mirrors.aliyun.com/ubuntu/ noble-proposed main restricted universe multiverse
