Bluetooth enabling button problem

[Sergio Benjamim]

I can`t enable bluetooth in gnome-control-center. If you disable it one time, then it's impossible to turn on it later.

Steps to reproduce:

1. click in bluetooth panel icon, and click in "Bluetooth Settings..."
2. turn off bluetooth, clicking in turn-on/turn-off button
3. try to enable bluetooth, it will turn off automatically (the button returns to turn off yourself)

How to workaround:

sudo rfkill unblock bluetooth

Status changed to 'Confirmed' because the bug affects multiple users.

I am having the same issue in an up to date (as of today) copy of Ubuntu 14.04. As stated, 'sudo rfkill unblock bluetooth' fixes the issue.

I have also experienced this in 14.04 and the suggested solution fixed it. You can also insert this line in a startup file whose name and location I forget!

JUST FOUND IT AGAIN:
sudo gedit /etc/rc.local
It will open the rc.local file. Just add the following line just before exit 0.
rfkill block bluetooth

This issue affects 18.04.2 LTS as well. I would say 'sudo rfkill unblock bluetooth' is a workaround. We need a permanent fix for this. Also, what might be causing this?
