Hello Julian, some notes on your answer. "If you want to use optional (deprecated) features of apt-key like adv" ->
How could I tell that "apt-key adv" is deprecated? Neither the man page nor the command says that adv is deprecated, and I couldn't find anything related in the first Google search result. "like almost everything else" -> what are you referring to? apt-key itself is deprecated? Why this is not written in the man page or in the output? Also, apt-key manpage only tells the user about the need of installing gnupg manually if the advanced options are required - dirmngr is not mentioned ANYWHERE. So: - I'm using a pattern that I've been using, successfully, for years on Ubuntu and Debian distros; - apt-key is installed; - gnupg is installed; - there's no other documentation about that anywhere (release notes? https://wiki.ubuntu.com/YakketyYak/ReleaseNotes ) OF COURSE as a user I think there's a yakkety bug. And, I might say, this is an example of a bad migration path; if I perform this command on Xenial $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv A1D267C030C00DCB877900ED939C61C5D1270819 [sudo] password for alan: Executing: /tmp/tmp.FAWWu2wvKx/gpg.1.sh --keyserver keyserver.ubuntu.com --recv A1D267C030C00DCB877900ED939C61C5D1270819 gpg: requesting key D1270819 from hkp server keyserver.ubuntu.com gpg: key D1270819: "Alan Franzoni (automated signing key) <automa...@franzoni.eu>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 I should AT LEAST receive a "pending deprecation" warning. On the contrary, it works 100% and gives me absolutely no clue on the fact I'm doing something wrong. That's not the way to go. -- 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
