ERPNext production installation problem on fresh ubuntu 16.04 LTS


i am trying to install erpnext production instance on fresh ubuntu 16.04 LTS 32 bit, but every time i face this problem:

i think this is due to issue in my connection stability but not sure i want your confirmation please.

apt-get update
apt-get- upgrade
