Hello, I'm trying to run the ros simulator (which previously worked on my system) but I'm getting an error stating that can't be found; I'll attach the full message below. I've searched the internet for a quick 'apt-get install x' fix, but I have been unsuccessful in finding a fix.

Here's a list of installed & updated packages:

        ros-kinetic-desktop \
        ros-kinetic-rviz-visual-tools \
        ros-kinetic-moveit-core \
        ros-kinetic-rosparam-shortcuts \
        python-catkin-tools \
        terminator \

I've tried re-installing multiple times using the commands :

wget && chmod 755 ./ && ./ catkin_ws_oroca indigo

as well as

curl | bash -s cws_oroca kinetic

I've also updated my ubuntu 16.04 system multiple times. does exist in the mentioned location. Below is the error summary when I try to run:

I don't know about oroca, but this error indicates that you've updated MoveIt, but haven't recompiled some of the other packages that depend on MoveIt. Versioning of shared libs (.so.X.Y.Z) was introduced by MoveIt devs exactly for this reason: MoveIt was upgraded in a non-bw-compatible way, ..

.. and in order to avoid 'silent' errors or hard to diagnose SEGFAULTs, changing the name of the libraries breaks applications on purpose.

You'll have to remove/recompile the oroca components that are now failing to load. That would seem to include verb_rviz_robot_state_rviz_plugin.

ok could you point me to a location that explains to do that or give the commands (to both of the comments)

Give commands for what? I don't have any experience with oroca, so I wouldn't know what to tell you.

I would recommend you try and ask oroca devs/maintainers how to rebuild / reinstall their application(s), particularly oroca-ros-pkg.

Thanks, just giving me the oroca-ros-pkg name is helpful. Will try now.

Trying to just remove then reinstall: E: Unable to locate package oroca-ros-pkg

oroca-ros-pkg is the name of the repository on the oroca github organisation. Not a debian / ubuntu pkg name.

got it, following whats available from

I've tried recompiling the MoveIt related packages and updating the aforementioned packages above. I know this is a long shot, but is there a simple list somewhere of all intended packages?

For reference I'm following these instructions:

and even purging then reinstalling results in the same error
