Did a full-desktop install on a netbook and workstation Ubuntu 12.04 that had a working Fuerte (/opt/ros/fuerte/ folder still there) & modified the .bashrc to only source groovy:

source /opt/ros/groovy/setup.bash
export ROS_MASTER_URI=   
export ROS_PACKAGE_PATH=~/ros_workspace:$ROS_PACKAGE_PATH

roscore gives following error:

$~/ros_workspace$ roscore
WARNING: unable to configure logging. No log files will be generated
Checking log directory for disk usage. This may take awhile.

Done checking log file disk usage. Usage is <1GB.

Cannot locate [roslaunch]Invalid <param> tag: Cannot load command parameter [rosversion]: command [rosversion roslaunch] returned with code [1].

Param xml is

Environment paths only point to groovy folders. Should I delete or move the /opt/ros/fuerte/ folder?

What should I check?

ahendrix advice led to discovering that several packages were indeed installed by pip, which somewhere in the process I removed. So installed pip from Aptitude. Also with another ROS Answer from hersh 'cannot run roscore due to error in rosversion', Oct 19 '12 uninstalled rosinstall, rospkg, rosdep, vcstools, catkin-pkg, pyYusb with "sudo pip uninstall PACKAGE", several times in some cases until that package was not found. However, now still have one error message from roscore,

~$ roscore

Traceback (most recent call last): File "/opt/ros/groovy/bin/roscore", line 62, in <module> import roslaunch

File "/opt/ros/groovy/lib/python2.7/dist-packages/roslaunch/", line 46, in <module> import rospkg

ImportError: No module named rospkg

Fixed by installing python-rospkg with aptitude ($sudo apt-get install python-rospkg) and apt-get update that did a lot of cleanup.
