To add your keys, please try this:

Open a Terminal from the menu Applications → Accessories → Terminal and type or better copy and paste a row a time then press enter:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com D0D3C959DB2035A6

Then type: (when the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

to update your system.

Hope this helps
