Hello, I was working on documentation last weekend with Freddy Martinez, and we noticed that the "extra repositories" section of the adding-applications portion of the Ubuntu docs covered entering a new third-party repository, but didn't cover adding the GPG key for that repository. Without a GPG key for third-party repositories, I believe that the user is issued a warning stating something to the effect that the repository couldn't be authenticated . . . do you want to continue, etc. Adding this instruction would assist users in those instances. I've validated the changes, but others may suggest different wording . . . Let me know what you think. Thanks.
