Hello I use ubutnu 10.04 LTS and ros unstable from the ubuntu repo While upgrading to the latest opencv, I had the error that some ros packages are incompatible with the new version, especially ros opencv. So I removed the conflicting packages, then libopencv could be installed But then unstable ros opencv cannot be installed anymore: I get the following error ros-unstable-vision-opencv: Depends: libopencv2.3-dev (=2.3.1+svn6514+branch23-1~lucid) but 2.3.1+svn6514+branch23-9~lucid is to be installed On the other hand I could successfully install electric ros with opencv Could someone please the dependency of ros unstable opencv to the new libopencv in ubuntu? thnx Regards, Moataz
