It looks like a recent update to OpenCV in ROS electric (as a system-wide package pulled in by ros-electric-vision-opencv) causes a conflict with the default Ubuntu library libcv2.1 (+libcvaux2.1 libhighgui2.1). With the electric apt-repository it is not possible to "apt-get upgrade" for all packages without removing the Ubuntu libraries. This will also uninstall third-party software which depends on the Ubuntu libs such as the video editing program "kdenlive" and its "frei0r-plugins".

The conflict must have happened in a recent update to vision-opencv as there was no problem before. Where lies the exact source of the problem, and how could it be fixed? Or is this just a temporary glitch in the apt repository? I feel like a ROS package should never conflict with a default system package on a supported platform. I wouldn't want to decide between the one usable video editing tool in Linux and future electric updates.

The behavior was observed on Ubuntu 11.04 and 10.04 (LTS).

Edit, more details: Updating ros-electric-desktop-full to 1.0.0-s1319593787~natty will upgrade libopencv2.3 from 2.3.1+svn6514+branch23-1~natty to 2.3.1+svn6514+branch23-5~natty. The former works fine, while the latter conflicts with Ubuntu's libcv2.1 (version 2.1.0-3ubuntu1).

Update 2: Given that this is a bug in the packaging of OpenCV (as it looks from the comments and replies), where would a ticket go? OpenCV trunk upstream? ROS package management?

I added more details about the affected versions. Is this an error in the packaging?

I'm getting the same issue too on ROS electric with 10.04. I feel like this issue came up before and it was fixed earlier but it's broken again now. Not sure what to do...

The conflict now seems to be resolved with the latest update to the debs:

sudo apt-get install libcv2.1 ros-electric-vision-opencv libopencv2.3
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libcv2.1 is already the newest version.
libopencv2.3 is already the newest version.
ros-electric-vision-opencv is already the newest version.

Package: libopencv2.3 Version: 2.3.1+svn6514+branch23-8~natty

Package: ros-electric-vision-opencv Version: 1.6.8-s1321009674~natty

I (again) observe this package conflict with the latest ros-electric packages on Ubuntu 11.04: ros-electric-vision-opencv 1.6.9-s1328567249~natty libopencv2.3* 2.3.1+svn6514+branch23-9~natty libcv2.1 2.1.0-3ubuntu1

Has this bug resurfaced? Cheers, Philipp

No, unfortunately not. If I manually compile from source I would need to compile all packages depending on libopencv (or vision_opencv) as well. This dependency conflict seems to affect the built .deb packages of opencv, distributed along with ros electric.
