Issue confirmed - the trusted-key option in gnupg sets the given key permanently to be trusted, not temporarily as was incorrectly assumed.<p>I apologize! To remedy the issue, please clear the trust value of key with ID &quot;DAFFB000&quot; by calling<p>gpg edit-key DAFFB000<p>and then command &quot;trust&quot;, set value to &quot;unknown&quot;, save and quit. After that, the trust value should be &quot;unknown&quot;.
If in any doubt, restore your trustdb from backup.<p>Update follows soon.
