network connection (wired and wireless) completely broken after upgrading to 4.4.0-67 kernel - Ubuntu 16.04 64bit

[Giovanni Mellini]

Hi,
I did an upgrade of my Ubuntu 16.04 and I installed last available kernel 4.4.0-67-generic.
My wifi won't work anymore (I had to boot with 4.4.0-66-generic that is working fine).
This is my lspci

Let me know if you need more info, this is a breaking regression

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1674109

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This is quite complicated because if I boot with the broken upgraded kernel (4.4.0-67) I cannot access Internet.

So I'm installing python-apport on my working kernel (4.4.0-66) and then I come back to the broken one to launch the request command.

I did some basic test and noticed that kernel 4.4.0-67 miss the wifi modules. When I try to do the following command
$ sudo modprobe iwlwifi

I receive an error message that say that this module don't exists
I attached the output of lsmod command on working and not working kernels, and there are a lot of missing modules in the broken one. So I think that the problem are the missing kernel modules

[Giovanni Mellini (merlos)]

When I launch apport-collect from the broken kernel I receive an error because wireless network is off and the script cannot contact launchpad.net
Is there a way to save the content offline and the upload to this bug?

[Giovanni Mellini (merlos)]

I booted with broken 4.4.0-67 and also wired connection is broken. So my laptop is completely unusable with the last kernel and I cannot access Internet.
So how can I send requested information?

[Kai-Heng Feng (kaihengfeng)]

$ journalctl -b > journal

Then attach 'journal'.

[Giovanni Mellini (merlos)]

Attached the output of
#journalctl -b

Launched on broken 4.4.0-67-generic kernel

[Kai-Heng Feng (kaihengfeng)]

Hmm, no iwlwifi, no wlp* interface.

Can you attach the output of `lspci -nnk`?
And output of `find /lib/modules | grep iwlwifi.ko`

[Giovanni Mellini (merlos)]

As I said in my comment #2 there are a lot of missing modules between kernel 4.4.0-67 and 4.4.0-66 (working). One of this is the wifi module.

Follow the output of requested commands, also the output of "modprobe iwlwifi" that as I said before failed:

Look like you don't have 'linux-image-extra-4.4.0-67-generic' installed. Please install the package.

I guess the 'linux-generic' metapackage somehow got removed. Please install it aswell.

[Giovanni Mellini (merlos)]

Tks Kai, you where right.
The image-extra package was missing

I installed it and now everything is ok
gmellini@goblinshark:~$ sudo apt-get install linux-image-extra-4.4.0-67-generic

Really don't know why was not installed during the upgrade.
I tried to check and install linux-generic metapackage but I didn't found

gmellini@goblinshark:~$ dpkg-query -l linux-generic
dpkg-query: nessun pacchetto corrispondente a linux-generic

I can confirm that now the problem is solved, tks for your support
Giovanni
