Re: Remove the wireless card

But, if you want 'FBI-level' disabling, ie - no possible way to hack it to work, then I suppose you could rip off the RF shield and then break the components off one by one until WiFi no longer works. I am NOT recommending you do this, but just pointing out it is "possible to remove the wireless ca...

Thank you for the reply, but I did use sudo when I tried to run it.
Then please post command and full error msg.
NB: note that it's '--configure' (with 2 dashes / minus signs and no space) not what you posted above. That was probably mutilated by an editor.

Re: Troubleshooting systemd Failure

If systemctl says it's still running then I would say it's the script that's the problem, not the service.
Add logging to the script to see where it goes wrong.

If the script ends / crashes systemd can restart it for you.
