I ran the Software Updater on my server rig, and now the networking doesn't work, even locally. There's no wifi and no ethernet.

I ran this:

$ cat /etc/netplan/01-network-manager-all.yaml

And got this:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

Is there a way to see what updates I recently installed to see where this might have stemmed from? Or a way to fix this entirely?

EDIT 1: Ran:

sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status

And received:

dpkg-query: package 'linux-modules-extra-5.15.0-70-generic' is not installed and no information is available

EDIT 2: Ran: ip a and received:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

Also ran iwconfig and received lo no wireless extensions.

EDIT 3: I also did the steps in the following post. It did not work. Ubuntu doesnt detect wifi or ethernet. *-network UNCLAIMED in Windows / Ubuntu dual boot

EDIT 4: sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status returns Status: install ok installed

And sudo lshw -C network shows that my network adapters are unclaimed.

EDIT 5: Input sudo modprobe ath9k and got modprobe: ERROR: could not insert 'ath9k': Operation not permitted

Then input ps aux | grep Network and got:

    May we see the result of: sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status Welcome to Ask Ubuntu. – chili555 Apr 24 '23 at 22:58
  • @chili555 Results are as follows: dpkg-query: package 'linux-modules-extra-5.15.0-70-generic' is not installed and no information is available Thanks for the welcome! – NoahTG Apr 25 '23 at 00:53
  • Can you boot into an earlier kernel version at the GRUB menu and does the wireless work there? Possibly helpful: https://askubuntu.com/questions/1464374/ubuntu-doesnt-detect-wifi-or-ethernet-network-unclaimed-in-windows-ubuntu-d/1464387#1464387 – chili555 Apr 25 '23 at 01:50
  • @chili555 It does not appear that I can. I also did the steps in that post, which unfortunately do not seem to have worked. – NoahTG Apr 25 '23 at 18:17
  • Did you download and install linux-modules-extra-5.15.0-70-generic or some other. The -70 is crucial. – chili555 Apr 25 '23 at 20:10
  • @chili555 Exact file name I downloaded from Ubuntu is linux-modules-extra-5.15.0-70-generic_5.15.0-70.77_amd64.deb – NoahTG Apr 25 '23 at 20:53
  • After a reboot, what does this report? sudo dpkg -s linux-modules-extra-$(uname -r) | grep Status and this: lshw -C network – chili555 Apr 25 '23 at 21:35
  • @chili555 Sorry for the lapse in contact. Updated the post with my results. – NoahTG May 01 '23 at 18:57
  • What is the exact response to the terminal command: sudo modprobe ath9k Is Network Manager running on this server? ps aux | grep Network – chili555 May 01 '23 at 19:57
  • @chili555 Refer to EDIT 5 – NoahTG May 03 '23 at 21:24
  • "ERROR: could not insert 'ath9k': Operation not permitted" Did you try to compile a driver? Please turn off Secure Boot and try again. – chili555 May 03 '23 at 23:19
