Disable blueman-mechanism.service at start up.

I am trying to reduce the boot time on my parrot OS.
command :-
systemd-analyze blame

blueman-mechanism.service takes about one third of my boot time.
I tried:-

  • systemctl disable blueman.service (didn’t work)

  • someone suggested replace AutoEnable=true to false in /etc/bluetooth/main.conf (main.config file is empty)

  • added “rfkill block bluetooth” on /etc/rc.local file (…not working)

When you say “didn’t work”, do you mean that you got an error after running the command, or the command ran but did not disable the service?

sorry for late reply, when i run systemctl disable blueman.service I get
Error Failed to disable unit: Unit file blueman.service does not exist.
