My symptoms and how I made them go away match this bug report exactly. The so-called duplicate bug #24061 has become a long discussion of many different bugs and user errors that can result in a GPG key error. Also it should be considered a bug that update-manager notices that something is wrong, but gives no clue as to what the problem is, whereas apt-get update at least gives clues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/893743 Title: Invalid signature for extras.ubuntu.com To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-extras-keyring/+bug/893743/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
