Untrusted Packages prompt

Hello all. Novice User here. Latest and greatest edition of Trisquel installed. 32bt

Began updating packages today using the Softwar Updater and got the message: "Requires installation of untrusted packages. This requires installing packages from unauthenticated sources."

I've seen this posted here before so just wanted to mention it.

I opted to load via Terminal instead. Success.
