Well I just unblocked the bluetooth via rfkill and did a:
apt install gnome-bluetooth

After that bluetooth was available within the system configuration and I
could connect to my bluetooth mouse.

Well, this solution is not really working or better to say it enables
bluetooth but has a really nasty side-effect.

If I do this two steps after the systemctl command tails tells me, that
my network card is disable as mac-spoofing did not work on the card.
So with these two commands I get bluetooth working again on the system
but instead the system uses all network connections which makes it not
really usable any more.
So it is not really a solution.

Is there a way to enable bluetooth without destroying the network
connection?
