Bug description:
  Yesterday I upgrade my Ubuntu to 17.10 from 17.04.

  I am using proxy given by my organization which is 200.0.1.254:99

  I have also manually set an IP address given by my organization which
  is 200.0.1.155

  There was no problem in Ubuntu 17.04 while updating or installing
  anything but after upgrading to Ubuntu 17.10 , I am not able to
  install anything (including 'software updater' and 'software &
  Updates) .

  There are no problem in browser , It working fine.(All other software
  working fine)

  When I try to install anything the I getting following error....

  $ sudo apt update
