Open a Terminal from the menu Applications → Accessories → Terminal:

copy the row below and paste into terminal window, then press enter

gpg --keyserver keyserver.ubuntu.com --recv 665F9AEFE1098513

copy the row below and paste into terminal window, then press enter

gpg --export --armor 665F9AEFE1098513 | sudo apt-key add -

Then copy the row below and paste into terminal window, then press enter:

sudo apt-get update

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

Then retry to update.

Hope this helps
