How do I force configuration of partially installed packages?

Whenever I run aptitude safe-upgrade, I get this output:

The following partially installed packages will be configured:
  cups gconf2 ufw update-manager 
No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 2 not upgraded.
Need to get 0 B of archives. After unpacking 0 B will be used.

How can I configure the four mentioned packages?

I tried dpkg-reconfigure gconf2 but that fails with

/usr/sbin/dpkg-reconfigure: gconf2 is broken or not fully installed

Solution 1:

Run these codes

sudo apt-get update

sudo apt-get clean

sudo apt-get autoremove

sudo apt-get update && sudo apt-get upgrade

sudo dpkg --configure -a

sudo apt-get install -f

This will clean and configure your packages

Solution 2:

This command fixed my problem:

apt-get --purge remove program_name

But of course you need to try also @ringtail answer.
