Update packages not signed?
Is this intentional? I just tried to update from the December 10th snapshot of the RC, to today's, and it failed because there's no signature. I could disable it, but I'm not interested in doing so for obvious security reasons.
Yes, it is intentional. Snapshots are not signed currently. Only images we "release" such as a full -RELEASE or an announced -RC get signed.
Eventually we may have a "snapshots" key to sign such interim updates but that's not in place just yet.
