I use ubuntu 10.04(lucid) 64 bit. I have been using diamondback for a while with no problems Due to some new code I need, which does not exist on diamondback, I tried to upgrade to unstable, so I removed all the diamondback stacks using synaptic and installed unstable one day after, ubuntu reported a partial upgrade regarding the ros unstable stacks. After that partial upgrade, some packages have been removed and could not be installed. I get the error msg: "error dependancy ros-unstable-opencv, but it cannot be installed" Among these packages are: ros-unstable-opencv ros-unstable-image-pipeline ros-unstable-simulator Same problem happens with ros-electric I had to revert back to diamondback Anyone else having problems installing either electric or unstable short ago?

I investigated further into the problem. Tits a dependancy problem and is caused by unmatched version of opencv. This is the error message I get when installing ros-unstable-vision-opencv: ros-unstable-vision-opencv: Depends: libopencv2.3-dev (=2.3.1+svn6514+branch23-1~lucid) but 2.3.0+svn5720+trunk-5~lucid is to be installed
