This is correct and intended behavior I believe. By default, packages archives shipped on the ISO images are signed with the cdimage key, and are trusted.
This means one can perform [dist-]upgrades from installation ISOs (note these are no longer produced by default). And enabled one to install packages from the ISOs (e.g. install updated openssl on a 14.04.0 host from the 14.04.1 server iso; another example install optional drivers off the desktop iso). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1363480 Title: ubuntu-keyring imports the Ubuntu CD Signing Key as a key trusted by apt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-keyring/+bug/1363480/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
