That command will only check whether you happen to have a key with "ubuntu"
in it in your personal keyring.

To check which keys are being used by apt, you would use "apt-key list".
However, it's clear from the error message that the original poster has the
correct keys.

The usual cause for such problems is a misbehaving transparent proxy, or
similar issue, which causes two of the files being downloaded (Release and
Release.gpg) to be out of sync with each other.
