in a terminal, try this

gpg --recv-keys CC919A31E23C5FC3
gpg --recv-keys 2EBC26B60C5A2783

gpg --export CC919A31E23C5FC3 | sudo apt-key add -
gpg --export 2EBC26B60C5A2783 | sudo apt-key add -

when it asks for a password, enter your user password, you will not see anything when you enter the password, that is ok, just hit enter after you type it in. it should only ask for a password on the first one, and that is ok too.

hope this helps
