Help, I was installing the Parrot Sphinx and send me an error

Installing the Parrot Sphinx at this line:
sudo apt-key adv --keyserver --recv-keys 508B1AE5
I got the next message:
Executing: /tmp/apt-key-gpghome.a44DL1hmMN/ --keyserver --recv-keys 508B1AE5
gpg: keyserver receive failed: Connection timed out
The server is out or something?
Its the first time that I got these message
