[Software] After debian testing update ethernet device disappeared!?

#1 Post by 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
WARNING: systemd-networkd is not running, output will be incomplete.

IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback - unmanaged
2 wlp6s0 wlan - unmanaged

2 links listed.
root@debian:~#
root@debian:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

6. I tried to change 'managed=false' to 'managed=true', but the problem still remains.
root@debian:~# cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false
