 Well -- that is recommended anytime one plans to install packages and
it has been some days since the last time packages were installed. It
downloads the list of available packages and their version/dependencies so
that changes can be determined.

 blueman is the package that claims to need pulseaudio (Debian site only
shows it as "recommended", not required
https://packages.debian.org/stable/blueman ). Do you really need a
graphical bluetooth manager?

"""
Blueman and PulseAudio

Users who want to use PulseAudio with a Bluetooth headset, in addition to
installing pulseaudio-bluetooth, may want to activate the PulseAudio plugin
of Blueman. This automatically loads PulseAudio Bluetooth module after
audio device is connected and plays all audio through the Bluetooth
headset. For more information see Bluetooth headset
"""

NOTE: plays all audio through the Bluetooth headset -- which may be any
paired phone...
