I am constantly getting same error when i do python manage.py runserver. There was no such error when i have ubuntu 15.10. This got started when i upgraded my ubuntu to 16.04. This question might look duplicate but i have tried solution provided to this question like i have applied the command dpkg --configure -a, i have done apt-get update,upgrade,dist-upgrade, clean, -f install. I have reinstalled python2.7 and python3 too but no success though. Here is my screenshot while trying to run my django application 
i got this after re-installing python
Could anyone please help me?
