Permanently STOP wpa_supplicant on Ubuntu 18.04
I just started an AWS Ubuntu 18.04 instance using their default image. I was surprised to see this process running:
$ ps auxww | grep wpa
root 792 0.0 0.2 45232 5380 ? Ss 15:43 0:00 /sbin/wpa_supplicant -u -s -O /run/wpa_supplicant
I believe this is to do with WIFI... well obviously AWS does not have WIFI on their instances, so how do I stop this useless process from starting on reboot?
sudo systemctl stop wpa_supplicant
sudo systemctl disable wpa_supplicant
