From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Ethernet plugged in but there is no internet. I have no idea what happened. I just took a normal update like I always do and after that it was all gone. WiFi connects no problem, but there is no internet. Unplugged Ethernet and replugged it back in. Nothing. I dualboot with windows, internet works fine there, so there is no hardware issue. Went into a live environment and chrooted into it and reinstalled network manager and still not a fucking thing. Not sure what these are now. I know about the lo one, but never seen the second wired connection or the virbr0. Any idea how to get my Internet back? I really don't want to reinstall the system because of this. And btw, I even tried a hotspot from my phone and a wire tether from it and still no internet.
System is endeavour OS with KDE on Wayland.

I lost internet after update. I had to

sudo systemctl restart NetworkManager

It then worked for me. Hope this fixes your issue too.

I'm not familiar with EndeavourOS, but I'll ask a few questions to get the troubleshooting process started:

With the ethernet cable plugged in, can you access your local router config page (if you have one)? e.g.: 192.168.1.1. If not, what happens when you ping the router's address in the terminal?

If you're able to successfully ping/access your router, can you ping a well-known IP address such as 8.8.8.8 (google DNS) or 1.1.1.1 (cloudflare DNS)?

Virb indicates a virtual driver. Are you running this Linux in a VM? Do you VM software installed. I think you may have installed the vmtools and it messed with your physical Ethernet. Virb is showing connected what do you get with an ip a? Does it show all the devices? Do any of them have an ip address?

That's why I don't use rolling releases (except debian-testing, which is actually stable). Because these kinds of things are bound to happen 1-5 times a year.

First step to check would be which packages were updated, and whether there are any .pacnew and .pacsave files in /etc
Cause that's really the only way a pacman update can fuck up networking, by installing a new config file for a networking-related package.

sudo find /etc -name *.pac*

also check if there are systemctl services that didn't come back up (most likely systemd-resolved)

sudo systemctl --failed

If there's only one physical ethernet port, I'm not sure why there are two wired connections. You try deleting the inactive one? Could have been a bug in an update script that hosed it.

Hey man I have no idea if it is the same, I'm a noon, but I had issues with a kernel update recently with my Debian home server and lost Ethernet too. I couldn't fix but I reverted the kernel update and voila my ethernet started working again. If this bothers you and like me you don't have much knowledge years you could try that .
