Traceback error during installation -Production (ubuntu 16)

Kindly find attached error during installation (python ./install.py --production). How can this be resolved?

This is sorted .Its a result of poor connectivity (timeout) while downloading wkhtmltopdf.

I have the exact same issue when downloading wkhtmltopdf, so now how should I retry the connection without redownloading installation requirements

I tried using the same command, it continued from wkhtmltopdf task, I think that’s the way
