roslaunch _whole_framework has errors due to only python3 present in Ubuntu20.04 #12

Hi! I'm using Ubuntu 20.04 and neotic ros installation.

My build completed successfully but on roslaunching the _whole_framework.launch, I get some errors with frame and objectStateArray in rviz. Upon further checking the logs in the terminal, it says /usr/bin/env 'python' : No such file or directory for process [map_frame_to_utm_tf_publisher-1] and other object initialization processes for v1, v2, p5, p6. I suppose it is because by default only python3 is provided with newer Ubuntu releases. Can it be fixed by simply changing to /usr/bin/env python3 in all those object initialization files? or something more needs to be done to migrate to python3.

Thanks

As workaround, changing the shebang is okay. See http://wiki.ros.org/UsingPython3/SourceCodeChanges#Changing_shebangs. Thanks for reporting.

edit: Fix is on the way

Please confirm and close if solved
