bluez hung upgrade from 14.04 to 15.10

[themusicgod1]

upgrade process to ubuntu wily got stuck for > 24 hours on :

Setting up bluez (5.35-0ubuntu2) ...
Installing new version of config file /etc/bluetooth/input.conf ...
Installing new version of config file /etc/bluetooth/main.conf ...
Installing new version of config file /etc/dbus-1/system.d/bluetooth.conf ...
Installing new version of config file /etc/init.d/bluetooth ...
Installing new version of config file /etc/init/bluetooth.conf ...

ended it with a ^C and kill -9 dpkg (there was a dpkg process left after the ^C but gdb did not glean any information from it), and then dpkg --configure -a successfully appeared to finish the install off.

claims to be installed and working, now:

just upgraded from 16.04 to 16.10 and this did not occur. At the very least, it appears that it's only affecting 14.04
