When running roscore with a new groovy install, i get this error:

This is caused by having a previously-installed "pip" version of rospkg which is out of date.

Fix this by:

sudo pip uninstall rospkg

repeat this until it says "not found"

then to be sure you have the latest:

sudo apt-get update sudo apt-get install python-rospkg

The "pip uninstall" version is supposed to work, but personally I did:

sudo rm -rf /usr/local/lib/python2.7/dist-packages/catkin* sudo rm -rf /usr/local/lib/python2.7/dist-packages/ros* sudo rm -rf /usr/local/bin/ros* sudo rm -rf /usr/local/bin/catkin*

to remove the old pip-installed versions. This should be safe for both Fuerte and Groovy users, because these tools are all now installed to /usr/ instead of /usr/local and are available as debian packages.
