[Testing - Bookworm] After debian testing update ethernet device disappeared!?

[fczwtyds]

Hello!

I use debian testing. Both wired and wireless network work fine. 2023-01-22 after update upgrade dist-upgrade and reboot, wired network broken while wireless network work ok.
I tried to solve the problem but wired network still not work. So I need your help, thanks.
I use debian testing from 2019.9 and I don't want to reinstall debian operating system.
Thanks a lot.

1. During the upgrade process I select 'Y' not 'N' to use new version's config except samba and grub.
2. After reboot, wired network broken and ethernet device do not exist and a new error message display at boot: Failed to start Load AppArmor profiles.
3. I remove apparmor and rename /etc/apparmor.d
4. I download and install: dpkg -i firmware-realtek_20221214-3_all.deb
5. ethernet device enp3s0(like this name) disappeared.
root@debian:~# networkctl

6. I tried to change 'managed=false' to 'managed=true', but the problem still remains.

You need to choose a form of network configuration.
See: https://wiki.debian.org/NetworkConfiguration

From the command output provided, the kernel sees your ethernet network adapter and has the correct driver to run it, r8169, so it's just a matter of configuration method you choose to use from the above link.

[fczwtyds]

I will do as your guidance.
Thank you very much.

I read and learned 'https://wiki.debian.org/NetworkConfiguration'.
'3 ways to configure the network' all need the name of the interfaces.
root@debian:~# ls /sys/class/net
lo wlp6s0
How to get the name of the ethernet interface?
Thank a lot.

The ethernet adapter is not showing up. Check that it's not blacklisted anywhere like in /etc/modules, /etc/modules-load.d/, /etc/modprobe.d/.

Thanks. I will read and learn and do as you say.

[fczwtyds]

1. /etc/modules is empty.
root@debian:~# cat /etc/modules

#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

2. There is no blacklist.conf file in both /etc/modules-load.d/ and /etc/modprobe.d/

Did you check the kernel logs (dmesg) ?

[fczwtyds]

Did you check the kernel logs (dmesg) ?

Thank you, I will learn check the kernel logs about net part.

[fczwtyds]

Did you check the kernel logs (dmesg) ?

I check and I found nothing. I do not know kernel logs a lot.

After dmesg, I search online and I read a lot of pages about this network problem.
Finally, I found the answer and now my wired network is working fine!

Thank very much to friends help me above!

The answer is:

r8168 Ethernet control chip is incorrectly driven by r8169 by Debian.
So, just three steps:
apt-get update
apt-get install r8168-dkms
reboot

Wish to help more friends!

Thanks for that solution. It sounds like your ethernet adapter is a little older than expected. In relation to that dkms package you needed to install, it's noted in the apt description that:

This driver should only be used for devices not yet supported by the in-kernel driver r8169.

so it's handy to know that.
