D-Bus setup failed: Name already in use

Solution 1:

Well, the message means that another/running daemon is using the same bus name.

• Check using:

  $ ps aux | grep blue
  sneetsh+  2226  0.0  0.0 333592  5432 ?        Ssl  08:00   0:00 /usr/lib/x86_64-linux-gnu/indicator-bluetooth/indicator-bluetooth-service

  Or system monitor (graphic user interface).

• Another option, d-feet, it is DBus browser. In the bottom left corner, you can see the owner process.

  

Then sudo kill it or sudo service ... stop it if it's service. For default Ubuntu setup, it has a service, so run:

rfkill block bluetooth
sudo service bluetooth stop

Run your local daemon then enable bluetooth again

rfkill unblock bluetooth

Without switching of bluetooth, the bluetooth service will re-spawn again.
