Bug Description

Ubuntu 14.04

'apt-get update' has started showing several warnings like the following, even though the keys are present:

sudo apt-key clean didn't help

The only ultimate solution was to remove all the keys from /etc/apt/trusted.gpg.d and run

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys KEY

for each key that was missing.

Have installed several fresh 14.04 and 14.04.1 LTS x64 servers straight off the iso image in the past few weeks, and this has presented itself on all of them.
