Sorry, didn’t make it home until today and not sure if you get notifications on edits. You will need a monitor and keyboard hooked up to your server as you will not have ssh access until the network config is “fixed”. I would do the below with the GPU removed, so you know 100% that your networking config is correct before mucking about further.
Step 1 - Create 99-default.link file
Add a /etc/systemd/network/99-default.link with the below contents.
# SPDX-License-Identifier: MIT-0
#
# This config file is installed as part of systemd.
# It may be freely copied and edited (following the MIT No Attribution license).
#
# To make local modifications, one of the following methods may be used:
# 1. add a drop-in file that extends this file by creating the
# /etc/systemd/network/99-default.link.d/ directory and creating a
# new .conf file there.
# 2. copy this file into /etc/systemd/network or one of the other paths checked
# by systemd-udevd and edit it there.
# This file should not be edited in place, because it'll be overwritten on upgrades.

NamePolicy=mac
MACAddressPolicy=persistent
Step 2 - Reboot and find new name of NIC that will be based on MAC
I forget if you have to reboot, but I am going to assume so. At this point, you can get the new name of your nic card and fix your network config.
ip linkshould list all of your nic devices, both real and virtual. Here is how mine looks like for reference, with the MAC obfuscated:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enxAABBCCDDEEFF: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master vmbr0 state UP mode DEFAULT group default qlen 1000
link/ether AA:BB:CC:DD:EE:FF brd ff:ff:ff:ff:ff:ff
3: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
link/ether AA:BB:CC:DD:EE:FF brd ff:ff:ff:ff:ff:ff
Step 3 - Fix your network config and restart network manager
You will need to edit your /etc/network/interfaces file so the correct card is used.
- Make a copy of
/etc/network/interfaces, just in case you mess something up. sudo vim /etc/network/interfaces(or whatever text editor makes you happy) It will need to look something like below. I have to have DHCP turned on for mine, so your config likely uses static. Really all you need to do is change wherever it says enp yada yada to theenxAABBCCDDEEFFyou identified above.
source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback
iface enxAABBCCDDEEFF inet manual
auto vmbr0
iface vmbr0 inet dhcp
#iface vmbr0 inet static
#address 192.168.5.100/20
#gateway 192.168.0.1
bridge-ports enxAABBCCDDEEFF
bridge-stp off
bridge-fd 0
- Restart your networking service. You shouldn’t need to reboot.
sudo systemctl restart networking.service
Step 4 - Profit?
Hopefully at this point you have nework access again. Check the below, do some ping tests, and if it doesn’t work, double check that you edited the interfaces file correctly.
sudo systemctl status networking.servicewill show you if anything went wrong and hopefully show that everything is working correctlyip -br addr showshould show that the interface is up now.
lo UNKNOWN 127.0.0.1/8 ::1/128
enxAABBCCDDEEFF UP
vmbr0 UP 192.168.5.100/20
At this point, if all is well, I would reboot anyways, just to make sure. If you add any GPUs, sata drives, other PCI device, disable/enable wifi/bt in the BIOS, or anything else that changes the PCI numbering, you don’t have to worry about your NIC changing.
I will have to give it a shot, though I am still pessimistic. I was kind of turned off by the whole Pocket or whatever advertisement thing it wanted to enable. Vivaldi has been fine for me so far.
