Hi Friends, Thank you for resuming this discussion; it is very important and relevant to many people. In general, of course we would love to provide binary packages of as many ROS distributions as possible on as many operating systems as possible. Unfortunately, there is a difficult tradeoff between the number of target platforms and the effort required by the package maintainers. The mailing list had a few discussions on this topic last year, which may be useful to frame this discussion: http://lists.ros.org/pipermail/ros-users/2013-May/053252.html http://lists.ros.org/pipermail/ros-users/2013-June/067832.html http://lists.ros.org/pipermail/ros-users/2014-January/068163.html On the roadmap, the primary target for Ubuntu Trusty (14.04 LTS) is ROS Indigo. Backporting ROS Indigo to Ubuntu Raring (13.04) seems to have limited utility, since 13.04 and 13.10 are already or nearly-already at EOL. Forward-porting ROS Hydro to Ubuntu Trusty LTS would seem to have more utility. Unfortunately, to produce a Hydro-Trusty binary release would require significant community effort to re-release all the packages. OSRF only maintains a small fraction of the available released ROS packages, so we are very sensitive to the existing time commitments of the package maintainers and hesitate to ask more effort from them. Our goal is for the generous efforts of the maintainers to provide the most utility possible to the largest possible user community. As has already been identified in this thread, building Hydro from source on other systems (Ubuntu Saucy, Ubuntu Trusty) currently works quite smoothly, with the caveat being the ~30 minute build time for Hydro-desktop, which is of course dependent on one's internet bandwidth and system performance. Taking these considerations into account, we think the best approach is to improve the experience of building ROS distributions from source, so they can be used more easily on distros for which they were not originally targeted. There are various things that could be done to improve the build-from-source process: better/easier documentation [1], better/easier software tools to automate the process [2], and so on. If you are interested in participating, ros-sig-buildsystem [3] would be a good place for such documentation/tool development and discussion. Cheers, Morgan [1] http://wiki.ros.org/hydro/Installation/Source [2] perhaps the tools could display cat photos in ASCII art during the build.
