My Ethernet connection stopped working. When I try to run an update from the terminal, I get a string of “Could not resolve host” errors and my browser can’t find server ip address.
In a failed attempt to fix the problem, I went into the network manager and told it to reset/forget the Wired connection settings. That didn’t help. I tried restarting systemd-networkd and dhcpcd. That didn’t help either. Please help.

Hope that helps.
This means your ethernet driver has correctly initialzed your device, so no problem there…
This indicates that you somehow have created a bridge config, maybe due to Docker, which are not working…
So check those…
This ipv6leak interface looks weird. Did you use some kind of VPN which maybe broke everything?
Look at the forum, the e1000e driver has some problems.
Also, I thinks it’s weird to use dhcpd and systemd-networkd in combination.
Indeed its either one or the other not both…
But i seem to have missed that, where did you notice him using those?
I had ProtonVPN installed. I uninstalled it, but the problem still exists.
Lets check a few places to see where things are configured…
networkctl status -a
Should give you info of what is configured where if it’s done using systemd.
Otherwise someone else might know how to query the NetworkManager configs, im not good with nmcli as i use systemd-networked…
networkctl status -a

Ok so we can conclude that your interface are NOT configured using systemd-network,
Most likely either NetworkManager or manual configs via some script using ip etc…
Your eno1
Shows that your ethernet port is actually configured, although uses a non-public IP, mostly used by VM’s or example code…
No idea where it gets those…
Your ipv6leakintrf0 interface is only configured with IPv6 and has Gateway fdeb:446c:912d:8da::1
That in combination with:
Led to dig a bit on the internet: https://duckduckgo.com/?t=ffab&q=fdeb%3A446c%3A912d%3A8da%3A%3A1&ia=web
You might also want to try disable Docker also, so you will be left with a bare system with respect to networking…
Well, that fixed the problem. pvpn-ipv6leak-protection was the problem. After I deleted it, the internet worked again.
Thanks
