W: GPG error: http://ams2.mirrors.digitalocean.com/mariadb/repo/10.0/ubuntu xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F1656F24C74CD1D8
W: The repository 'http://ams2.mirrors.digitalocean.com/mariadb/repo/10.0/ubuntu xenial InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: There is no public key available for the following key IDs:
F1656F24C74CD1D8  

The key can be installed with this command (found it in the Dockerfile for this project)
apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys F1656F24C74CD1D8
