Comment 1 for bug 1749063

So this turns out to be a missing gnupg2 package (note the *2*, it's important). actually dib has this in bindep, but the devstack-based test isn't using that (a bug for another day)

there is also a bug about the package of this -> https://bugs.launchpad.net/ubuntu/+source/zypper/+bug/1639428
