It all started just that little amount of time ago, I was failing horribly at configuring OpenVPN and decided to reboot. Upon rebooting, I couldn't access the internet. I figured it was my router since it's given trouble in the past, even on Windows. However, after rebooting the router and confirming internet access with a cellphone, I failed to access the internet from my machine. After doing vague amounts of research, I decided to pull up information via GUI and discovered that I had ipv6 addresses, but not ipv4 addresses. Which at the very least allowed me to migrate from the "linux no wifi" style searching to the seemingly less ridiculous "Ipv4 how to enable linux" or perhaps it's seemingly more attractive cousin "how to reset networking config Ubuntu" (Keep in mind I was more thorough with my searches). After reading a fair amount of media and playing with config files in /etc for about a half hour in total like a fiddle, I reboot and now my ethernet card is disabled. I'm currently typing this from a Live Debian USB. My system is running Ubuntu 18.04.2 LTS.

Is there a question?
You want to configure the network interface on an Ubuntu machine?

First look at the docs.
https://help.ubuntu.com/
https://docs.ubuntu.com/
https://help.ubuntu.com/lts/ubuntu-help/net.html.en

Does the machine have a fixed IP or gets one from a DHCP server?
What is the output of
ip addr
ip route
What IP address is the router at?

You need an IP, a route to the outside world, a DNS server.
The internet router will have to accessible from the buntu box. Look at your subnet mask.

Post your network managers config file.

Perhaps I should have put that differently, I apologize.
What I am looking to do is to completely reset any and all network configuration
via the command line or perhaps just handle reassigning ipv4/inet addresses
to my ethernet connection and wifi card. As stated earlier, I am not even able to detect a functioning ethernet connection. The router address should be 192.168.0.1. My IP addresses are dynamically assigned, I've considered making it static. However, I want to focus on regaining internet access for the time being.
I am completely clueless as to where my Network Managers config file and to
be completely honest I don't exactly understand anything about said "manager", sans the
name and reason for existence. I am competent with respect to command line use
and handling config files, however I don't exactly possess Arch-Tier Competence.
I have provided the output from the requested terminal commands.

I again apologize for the badly executed prompt. Since at the time of writing
this is my only machine, you could imagine the lack of internet access
not being super fun. Thanks for your time.

I've never used buntu, your docs should give you info.

2: enp1s0: is your wired interface. And it is down. It either is unplugged or is set in down state.
https://help.ubuntu.com/lts/ubuntu-h...onnect.html.en
https://help.ubuntu.com/lts/ubuntu-h...manual.html.en

3: wlp2s0 is your wireless interface. And it has an IP6 address. Give it an IP4 address and you'll also probably need to configure the WPA key. Also check to see if you have an available DHCP lease on your router. If you have been troubleshooting, it is possible to continue to another lease over and over.

The wiki calls for using Gnome 3.

I uninstalled Gnome 3 and any Ubuntu related things a while back.

Help, I've tried to reinstalled Gnome 3 but I keep getting connection failures even when forcing ipv6!

It appears I must use the good ol' terminal, I gosh darned goofed.

Could I get some 'Buntu-Oriented CLI technique?

I hope for the best, good day.

anbox0 probably has something to do with anbox, the android emulator, which was definitely in alpha stage last time i looked. It actually almost borked my system once, don't remember the details anymore. It digs itself deep into the OS.

pan1 is not something i ever heard of.

My guess is you should get rid of both. Undo whatever you did.

And in the future remember that Linux gives you full control over your system, with the responsibility that entails.

Pardon, but I should highlight the fact I had anbox installed for at least 3 months and my network card seemed to work just fine. In addition, this problem only started after a reboot after the installation of OpenVPN and failing to use it correctly. I understand that the problem lies in a configuration issue between with the network card and nothing else, I literally just need to know what I can do without the ability to install packages (using "dpkg -i" doesn't seem to work) What "network.cfg" do I have to fiddle with to regain internet access "pan" I believe is related to OpenVPN. I need the Expert who knows the things I don't, help please. What you've told me isn't working.

(OK, I'm just going to make this a full quote because I can already see where all this is heading.)

I stand corrected on anbox. Apparently it became usable recently.

You (rightly) didn't do what I told you, so it also can't be working.

Fact is, your ip route is wrong.

Mine looks like this:
Make yours something like that (the most important bit is the device - it should be either wlp2s0 or enp1s0).
This is not a unique problem, so a web search should provide you with the commands.

If that works - how to make it persistent - well I think Ubuntu uses some sort of net configuration software that I'm totally unfamiliar with.
But you've been pointed to Ubuntu docs already, I'm sure you can find sth there.
