Workaround is to remove any phone device paired in bluetooth if it's not needed. Alternatively, stopping the ofono service should also let NetworkManager run properly. ** Description changed: + WORKAROUND: + + - Remove any phone device paired in bluetooth if it's not needed + OR + - Stop the ofono service with 'sudo service ofono stop' + + Removing the phone pairing will let NetworkManager run succesfully, but + will make bluetooth DUN/PAN unavailable.
