新安装的debian12，用的是net install，安装的时候提示dhcp没配置好，问是不是以后再设置网络，选是，然后也没有安装软件包，安装完之后就是纯字符界面，我修改了一下network/interfaces并重启网络服务也不管用。
是不是不能用net install？如果继续手动配置网络并安装好各种组件会不会非常麻烦？谢谢了

这是搜的网上的答案，估计是系统bug


Thanks for replies – I solved the issue, even though I’d still like to know the reason, why the setup behaves totally different than the live system.

Quick summary: When I try to install the Debian 12, network just doesn’t work.
It doesn’t matter whether I try to use DHCP or a static-IP during setup, just doesn’t work.
When I boot any live-image (I tried several) network works perfectly fine, and even if I ignore that not-working-network during installation, network doesn’t work on the fresh install either.
It also wasn’t a driver problem, which is what I initially thought, I found out the setup also uses the Intel e1000 driver …

So anyway, to cut a long story short, for whatever reason, the setup and fresh installation uses the wrong network interface!

/etc/network/interfaces on setup / fresh-installation:
Iface enp2s5 inet dhcp

/etc/network/interfaces on the live-image:
Iface enp0s25 inet dhcp

So when I found that out, it was obviously an easy fix, replacing “enp2s5” with “enp0s25” and the network works!
I’d never expected that!

Do you have any idea, why the live-images uses the correct interface enp0s25, while any installed system (and the setup) uses a (non-existing?) enp2s5 interface?

您指的其实是network manager吧

systemd和nm是两套不同的方案，一个配置文件是/etc/NetworkManager/NetworkManager.conf，一个是/etc/systemd/network/xxxx.network。现在systemd是主流了

赖在 /etc/network/interfaces ， 能赖多久赖 多久
