I don't know how to fix the error. But you should follow the official doc:

    $ curl -s "https://packagecloud.io/install/repos..." | sudo bash

    $  sudo apt-get install php7.0-phalcon

Now in ccertain linux distros (eg mint) you may encounter errors. I found this video to remove those errors. You simply change linux version in the file: /etc/apt/sources.list.d/phalcon_stable.list For example, replace "/mint/ tessa" with "/debian/ stretch" . Watch the video if you are still confused.
