一、配置软件源

编辑/etc/apt/sources.list，添加下面地址(bookworm为debian12的代号，其它debian需要更换代号)

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-backports main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware

更新源

sudo apt update

二、配置静态地址

查看网卡名称ip a
编辑网卡配置文件vi /etc/network/interfaces

auto ens32
allow-hotplug ens32
iface ens32 inet static
address 192.168.88.150
netmask 255.255.255.0
gateway 192.168.88.2

重启网卡systemctl restart networking.service

配置dnsvi /etc/resolv.conf

nameserver 114.114.114.114
nameserver 8.8.8.8
nameserver 8.8.8.4
