When trying to setup a blue tooth speaker in Mint Cinnamon 18.2 I get the following message : Bluez daemon is not running, blueman-manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started. Blue tooth works perfectly and slick with the same speaker from my Samsung S5 phone. After perusing the internet other people were having a problem with the Blueberry manager and had success with the Blueman manager so I replaced Blueberry with Blueman without success . Maybe this is compounding the problem. Are you able to assist?
