"keyserver.ubuntu.com: Connection refused" during build

[DewiBrynJones]

https://github.com/MycroftAI/docker-mycroft/blob/master/Dockerfile#L18 :

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F3B1AA8B && \

fails with the following:

--recv-keys
F3B1AA8B
gpg: requesting key F3B1AA8B from hkp server keyserver.ubuntu.com
?: keyserver.ubuntu.com: Connection refused
gpgkeys: HTTP fetch error 7: couldn't connect: Connection refused

Makefile:4: recipe for target 'build' failed

probably because of a blocked port (https://unix.stackexchange.com/questions/75892/keyserver-timed-out-when-trying-to-add-a-gpg-public-key) at my University.

Changing that line to

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys F3B1AA8B && \

resolves the issue.
