I need help installing some 3rd party programs

[5150Jim]

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.
