All 8.0 and Mitaka repositories are signed
E.g. http://mirror.fuel-infra.org/mos-repos/ubuntu/8.0/dists/mos8.0-holdback/Release.gpg

"the public key is not available" means the public key hadn't been imported to the keyring

I was getting error in the Mirantis 8.0/Fuel 8.0 deployment on the Controller Node.
Checked the Puppet Logs :
ERR Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install swift' returned 100: Reading package lists...
While running the apt-get update on the node gave the below error :
W: GPG error: http://mirror.fuel-infra.org mos8.0-holdback Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY BCE5CC461FA22B08

Resolved by getting a fix from friend Arijit Bose as below :
