Hi everyone, it looks like something has broken the live debian releases. Upon accepting updates (confirmed on Lucid 32 bit), ros-electric-vision-opencv is removed (and all packages that depend on this). If attempting to re-install, you receive the error: "sudo apt-get install ros-electric-vision-opencv Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ros-electric-vision-opencv: Depends: libopencv2.3-dev (= 2.3.1+svn6514+branch23-8~lucid) but 2.3.1+svn6514+branch23-6~lucid is to be installed E: Broken packages" There appear to be several ROS answers related to this and a failed OpenCV release related to SSE optimization: http://answers.ros.org/question/2787/illegal-instruction http://answers.ros.org/question/2839/illegal-instruction-when-using-image_view-with http://answers.ros.org/question/2882/about-compiling-opencv-programs-outside-ros And another related to broken installations and the specific OpenCV release: http://answers.ros.org/question/2881/unmet-dependencies-in-ros-electric-desktop-full To make matters worse, the debbuild status page is currently 503 unavailable, so I'm not sure if someone is fixing things or if that's an unrelated problem, but I don't see anything on Hudson that looks like it's building a fix. http://www.ros.org/debbuild/electric.html http://build.willowgarage.com/ Just wanted to make sure everyone was aware of this situation. Thanks, - Chad
