Hello list

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?

Best regards

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

This should be resolved now if you run 'apt-get update'

Thnx for the reply. I tried to make an update, no new packages appear, I live in germany, so I changed the repository server to USA server (not that it should matter), and still got no updates

Did you run "sudo apt-get update" after you changed the repository? I was able to update on my machine. Also, not sure what you mean by 'USA' server as we only run 1 server. You need as your repository.

sorry about the 'USA' server, for a minute I thought ros packages are being pulled from the ubuntu server, my mistake

so, do you still get the opencv error?

nop.I was using the freiburg repo, now I switched to the main ros repo, and I can install ros unstable like charm. Many thanks for the quick reaction
