Recently figured out how to install proxmox on my old laptop. Installation went great, but as I try to access the web interface i couldnt connect to the ip adress I was given. Tried switching ip adress, but eventually found out that I didn't even have an internet connect. And since my laptop didn't have an ethernet port, I had to buy an usb to ethernet adapter.

Sadly it still doesnt work though. I tried to follow some of the other threads on this issue, but couldn't get it to work. So I decided to make my own thread. I'm also very new to this, so if there is any information that I need to share, for you to help me, just ask.

Thanks in advance

This is what I get when I type "ip a". I noticed it says "DOWN" on my ethernet and wifi, but don't know how to fix it. (There might be some typos, sorry)
Bash:
root@pue: # ip a
1: lo: LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
        valid_lft forever preferred_Ift forever
    inet6:1/128 scope host noprefixroute
        valid_lft forever preferred_lft forever

Hi.
You can try to bring the interface up:
ip link set enx00e04c68069f up
Does the eth adapter have any LEDs? Are they lit?
If not, try to replace the eth cable.
Does the adapter work when connected to some other computer and to the same port of the switch / router?
Does it light up the LEDs then?

Hi, thanks for the reply
So my cabels, computer or adapter, doesn't have any lights
I tried "ip link set enx00e04c68069f up", but it doesn't seem to have any effect
I tried replacing the eth cable, but didn't change anything
Also tried using the adapter on my main pc, which worked fine
 
My idea at the moment is that you can boot this laptop from a Debian Live CD and see whether the adapter works in it, or not.
Then from some Ubuntu Live CD.

It will show if the reason is in the laptop or in the operating system (particularly in Proxmox).

Sorry it takes a while to respond. I work quite a bit. I'll try this out tomorrow

So, I got into a work accident, and I'm having a hard time using one of my hands. Therefore there might be some extra delay in trying to get back to you. It's fair enough if you don't want to wait. Sorry for that.

But I've tried looking at the installation of a debian live cd. Got this far, https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/, but don't know which one to install. gnome, kde, cinnamon and so on. Does it matter which one I pick?

No reason to be sorry. That' OK. Take your time and get well :).
In case I won't read your future post, someone else will probably try to help you.

No need to install other OS (unless you want to remove Proxmox from your laptop).
LiveCDs' main purpose is to be able to try / compare / repair the OS which is already present on the disk, etc. without installing live OS on the disk.

For your test of ethernet adapter it shouldn't matter which type of graphic environment you'll choose. E.g. I don't like Gnome, but GUI selection is mainly a question of taste.

I've flashed an usb with the "debian-live-13.1.0-amd64-lxqt.iso". Do I still have to go through the entire setup procedure? I'm following a tutorial, and he warns that the installation would remove everything on the harddrive. From my understanding, a live usb installation, shouldn't be on the harddrive? Should I just not do the full installation?
For reference this is the tutorial I'm using. I'm at about 5:00, How to install Debian 12 using live USB. (I'm doing it with Debian 13.1.0)

Tried just getting a connection, without doing the full setup. It worked. I have an "active connection" with the ethernet to usb adapter. Even used "ping 1.1.1.1" in the terminal, and it worked.
So the problem might just be proxmox?
