when I try to install darkflow from ubuntu, there's error message
E: The repository 'http://darkflow.org/Ubuntu.amd64 xenial Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Hi @adisis !
I will take a look at it and update everything accordingly.

Thanks for the feedback!
