Hi! I am the upstream maintainer of https://github.com/mvidner/ruby-dbus and I've found this bug by accident (via a Twitter search)
The suggested fix works when I run the tests locally: https://github.com/mvidner/ruby-dbus/compare/master...mvidner:use-dbus-run-session?expand=1 But not so in build environments. > Unlike dbus-launch, dbus-run-session is better-designed for the use > case of wrapping a regression test, and does not have an X11 dependency; > distributions are expected to ship it in the same package as > dbus-daemon. Unfortunately that seems not to be the case. Travis on Ubuntu Trusty fails: https://travis-ci.org/mvidner/ruby-dbus/builds/159596244 and also openSUSE-42.1 is still packaging dbus-run-session in the X11 subpackage: $ rpm -qf /usr/bin/dbus-run-session dbus-1-x11-1.8.16-7.1.x86_64 I think I will need to find a way to install dbus-run-session in the Travis environment, and get the openSUSE package fixed.
