what is problem ?

The problem is that you are running the command with elevated privileges (as root?) and do not require 'sudo' on the apt-key add command.

If you see ": #" you are already running with elevated permissions.
If you see ": $:" you need to add sudo

Drop 'sudo' from the second half of the command after the "|"

The command should look like this:

wget -O- http://downloads-global.3cx.com/downloads/3cxpbx/public.key | apt-key add -
