Since yesterday I get the following error when attempting to
apt-get update on Precise.
W: GPG error: https://apt.dockerproject.org ubuntu-precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F76221572C52609D
Does this require a fix by circleci? If so is it likely to happen now that Precise is EOL’d? (April 2017)
