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

inet6 ::1/128 scope host

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.

and got modprobe: ERROR: could not insert 'ath9k': Operation not permitted
Then input ps aux | grep Network
and got:
