Title:
[jammy] DNS issue triggered by command "udevadm trigger --subsystem-
** Description changed:
[Summary]
In jammy server image, when we use NetworkManager as netplan renderer, we may
have DNS issue after executing command "udevadm trigger
--subsystem-nomatch=input" as super user, the udevadm command may also be
executed when we use "apt install XX" or
bin/bash
set -ex
counter=1
while true; do
echo "$(date): test round ${counter}"
counter=$((counter + 1))
sudo udevadm trigger --subsystem-nomatch=input
ping google.com -c 2
sleep 0.5
done
