package blueman 2.0.4-1ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

AFTER REINSTALL FOLLOWING SHOWED UP, SO looks like the issue can be resolved with reinstall.

BUT this BUG arose when doing debootstrap.

dan@ACER:~$ sudo dpkg-reconfigure blueman
[sudo] password for dan:
/usr/sbin/dpkg-reconfigure: blueman is broken or not fully installed
dan@ACER:~$ sudo apt-get install blueman
