This tool is not compatible with the new version of Python (python3, pip3 etc) so it gives errors that python-pip has no installation candidate. This is because Python2 is not supported anymore and this tools has not been updated and required python-pip (python 2 pip). We do not want to downgrade to python2 and this tool should be updated and be compatible with Python3 pip3, python3-pip etc.
