[Bug 2084695] Re: Kernel update through apt leaves the system with no working network connection.

Hi Pedro, Nicolas,

This is all very interesting. Let's look at the difference between -45
and -47:

ubuntu-noble$ git log Ubuntu-6.8.0-45.45..Ubuntu-6.8.0-47.47 --oneline
e46076274f5d (tag: Ubuntu-6.8.0-47.47) UBUNTU: Ubuntu-6.8.0-47.47
cd3da1a0fdfc UBUNTU: link-to-tracker: update tracking bug
978f407df30d UBUNTU: Start new release
5017a6a30cd4 (origin/master-next--s2024.09.02-1) netem: fix return value if duplicate enqueue fails

A single commit... (it was a CVE patch cycle you see)

Yes, this commit was in the net subsystem, but if it contained a
regression, it wouldn't have the effect of your devices not showing in
boot logs.

I'm thinking more that maybe you are missing linux-modules, or linux-
modules-extra packages?

Can you do a:

$ dpkg -l linux

or a

$ dpkg -l *6.8.0-47*

and check that linux-modules-6.8.0-47-generic and linux-modules-
extra-6.8.0-47-generic is installed?

What happens if you:

$ sudo apt install linux-image-6.8.0-47-generic linux-modules-6.8.0-47-generic linux-modules-extra-6.8.0-47-generic linux-headers-6.8.0-47-generic
$ sudo update-initramfs -c -k 6.8.0-47-generic
$ sudo update-grub
$ sudo reboot

which installs the kernel packages, rebuilds the initramfs, updates grub
and reboots?

If that fails, can you boot into 6.8.0-47-generic, save dmesg to a file,
and upload it?

$ sudo dmesg > 47-dmesg.log

I'll see if the devices really aren't showing up at all then.

Thanks,
Matthew

Title:
Kernel update through apt leaves the system with no working network
connection.

Status in linux package in Ubuntu:
Confirmed

Bug description:
I am using Ubuntu 24.04.1 LTS. After the upgrade to kernel 6.8.0-47
from 6.8.0-45, for the first time, Ubuntu was unable to recognize my
ethernet, wifi and bluetooth. None of these issues occurred before
since they were automatically recognized and configured by the
installer. The only solution I found was to revert to 6.8.0-45.
