Connection to bluetooth headsets fails

[Hadmut Danisch]

Hi,

since upgrading to 17.04 I can't connect to bluetooth headsets anymore. Headsets are found and listed as devices, but when trying to connect, there's an error

blueman.bluez.errors.DBusFailedError: Protocol not available...

syslog says:

Hi ! Have you tried to install pulseaudio-module-bluetooth ?
