Additional Software wont install

[RAB302]

I'm new to Linux Lite, just installed it. working fine, but when you goto System>Addition Software>enter your password, and then enter any of the options (1 to 25) none of them wont install. Just an Error window comes up, it cannot be installed.  Additional Info: I'm using Dell Latitude D620 laptop.
Any Help with this is appreciated!

Run this, and try again.

Code:

sudo dpkg --configure -a
