APT recommends gnupg, and gnupg recommends dirmngr, so all is working as intended. If you want to use optional (deprecated) features of apt-key like adv, you have to manually install gnupg. If you want to use optional features depending on key servers, you have to install dirmngr manually.
The adv option is deprecated, like almost everything else. Drop files in trusted.gpg.d instead. The recommends on gnupg will be downgraded to a suggests at a later point. ** Changed in: apt (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634464 Title: cloudimg apt missing dirmngr To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1634464/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
