Public bug reported:
I have two Kubuntu machines based on Ubuntu 20.04, x86_64. The machines
use a script to auto-update each night. The script performs an 'apt-get
update && apt-get upgrade' each night around 4:00 AM as a systemd
service.
When I woke this morning I could not connect to either machine. The
wired network connection cycles from dectivated->activated->deactivated.
It is just bouncing. I enabled wifi and tried to bring up the network
but I had other problems. I seem to be getting a 10.0.0.xxx address so
the network is also down.
Dmesg does not show errors related to networking.

The one hint I have is, /var/log/apt/history.log shows a new linux-
firmware was installed on both machines. This appears to be the only
change on the day before trouble started:
Start-Date: 2022-03-04 04:19:40
Commandline: apt-get upgrade -y
Upgrade: linux-firmware:amd64 (1.187.26, 1.187.27)
End-Date: 2022-03-04 04:20:24
I've tried reinstalling network-manager with no joy.
Any help is appreciated.
