This will just download the key, but not make Update Manager use it to
verify the downloads. Instead, try the following command:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9BDB3D89CE49EC21

It's probably not an ownership problem, so chown won't help.
I think you need to stop other users accessing the .gnupg directory,
so 'chmod 700 /home/cjm/.gnupg' should do the trick. You might need to
change the files inside the directory too: something like 'chmod
--recursive go-rwx /home/cjm/.gnupg/*'

Obviously, don't type the ' quotes on the command line! :-)
