I am new to ROS. I completed ROS-Kinetic installation in Ubuntu-16.04 system by following steps provided in below page. http://wiki.ros.org/kinetic/Installation/Ubuntu and I am able to launch "roscore" without any issues since installation.

I am facing below issue since yesterday while launching 'roscore'.

Error Log:

    ... logging to /home/senthil/.ros/log/28d897a8-31dd-11ea-880e-0c5b8f279a64/roslaunch-senthil-OptiPlex-7010-21574.log

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

Param xml is <param command="rosversion roslaunch" name="rosversion"/>
The traceback for the exception was written to the log file

I even tried uninstalling ROS from my system couple of times and that didnt help. It is much appreciated if anyone can help me in resolving this issue.

Thanks in advance.

I believe this is a duplicate of #q301850.

Note how you have anaconda3 in the paths to your Python modules/packages and interpreter in the traceback.

That is your problem.

And an observation:

I see people posting this a lot. I'm unsure as to how that is ever supposed to help in situations like these. Only a very small set of problems could potentially benefit from reinstalling (some) packages.
