The new QuickBuild 'axis' archive key fingerprint is: 414A 7361 20EA D92E AE8B 24AE F7F9 96A6 00A5 8606 The new my personal key fingerprint is: 453E B7B3 8E49 1AE1 108C D8BC 608F 5293 A04B E668 You may add both updated signing keys to your system with this command: sudo apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 00A58606 A04BE668 Soon, all my archives will be signed by the new key.
