Unfortunately changeset 17145 was not included in the latest available xpra 2.2 beta which is from yesterday morning. Could you trigger a new xpra 2.2 beta build for centos including that changeset?
    I wasn't 100% sure which specific distro versions you needed here, as
    you've mentioned both "apt-get" and "CentOS", so I've pushed some new
    2.2 beta 64-bit builds for Ubuntu Zesty and Artful, Debian Stretch, all
    current versions of Fedora and CentOS 7.4.
    And for good measure, also MS Windows and MacOS.
    
Sorry, that I mentioned CentOS. The docker image is using Debian Stretch. Either the beta build did not work or it is still in progress. The Packages file for debian stretch amd64 is currently empty (see https://xpra.org/beta/stretch/main/binary-amd64/ ) and I can’t install from the repository anymore. Can you have a look?

    You haven't installed dbus or the python bindings for it.
    These features are optional, to avoid the warning you can use:
    "--dbus-launch=no"

I couldn’t find the --dbus-launch option in the xpra manpage ( https://xpra.org/manual.html ). Therefore I didn’t know about the switch. I did not check the manpage of the binary in the docker container though…

Thanks for all the explanations!
