Looks like your installs of java and Opera are causing this. You can go to Software & Updates (Menu->All->Software & Updates) . Choose the Other Software tab and uncheck the items referring to launchpad.net/java and the one referring to Opera.
OR
You could uninstall them by trying:
Code:
sudo apt-get purge opera
sudo apt-get purge java
Then re-try what was mentioned before.
Deselect the software source that refers to the launchpad ppa for java. Then try what was mentioned before with Lite Software.

It is deselected. Maybe I need to reboot?
After reboot, run Install Updates (Menu->Favorites->Install Updates), then try opening Lite Software.

Code:
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update
Then try opening Lite Software again.
Okay I rebooted & tried again.
Still got an error
W: GPG error:

Install Updates running!!!
To remove the GPG public key error:
Code:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3BDAAC08614C4B38
sudo apt-get update
AND
If you installed java using the aforementioned link
http://forum.pcmech.com/threads/installi...te.231503/, you need to uninstall it using:
Code:
sudo apt-get purge oracle-java7-installer
sudo apt-get purge oracle-java7-set-default
sudo apt-get update
Then try installing Java via Lite Software.

WOW!!! everything went smooth. I even installed Java via Lite Software like you said. Then I went back and installed Dropbox, Music Player, Video Editing Software, VirtualBox & Webcam Software.
Thank you.
Now I just need to get my printer working.
I'm looking into this from a comment that was earlier in the topic.
And this looks like a good resource on your printer. When they mention Synaptic Package Manager, you get to that in Linux Lite by going to Menu->System->Install/Remove Software.
