[DragonForgedTheArtist]

I get the following error trying to run grizzly in ros and gazebo

Hi @dragoneagle could you double check you have all the need dependencies installed using rosdep install --from-paths src --ignore-src --rosdistro=$ROS_DISTRO -y inside you workspace?

[DragonForgedTheArtist]

That didn't fix it. I'm sorry I forgot to mention that i am running kinetic on ubuntu 16.04

[tonybaltovski]

Pull down the latest grizzly repo, this was fixed in there. If you add the Clearpath Packages, you can install the debs using apt.

[DragonForgedTheArtist]

Didn't work installing them from the repository either. I even tried to reinstall from scratch. I'm not going to worry about it for right now. As long as I don't need it for any of the tutorials I'm going through it will be ok.

Could you run git log -n 1 in grizzly and grizzly_simulator repos?

[tonybaltovski]

Those are the correct versions. Did you re-run rosdep? Lastly, you could just install velodyne_description via apt.

[DragonForgedTheArtist]

I did rerun rosdep and ros-kinetic-velodyne-description is already installed
