BigChainDB Installation Issues (Connection Reset)

Hello

I am trying to install bigchaindb via pip3.5 on Ubutu 16.04 on a Oracle VirtualBox. But every time I am getting a 104 (Connection Reset by Peer) on execution of command sudo pip3.5 install bigchaindb
[Error_Trace_log.txt](https://github.com/bigchaindb/bigchaindb-examples/files/885796/Error_Trace_log.txt)
.

I've followed below steps till now as per recommendations @ https://docs.bigchaindb.com/projects/server/en/latest/quickstart.html and was able to install rethinkdb correctly.

source /etc/lsb-release && echo "deb http://download.rethinkdb.com/apt $DISTRIB_CODENAME
main" | sudo tee /etc/apt/sources.list.d/rethinkdb.list
wget -qO- https://download.rethinkdb.com/apt/pubkey.gpg | sudo apt-key add -
sudo apt-get update
sudo apt-get install rethinkdb
$ sudo apt-get update
$ sudo apt-get install g++ python3-dev libffi-dev
$ sudo apt-get install python3-pip
$ sudo pip3.5 install --upgrade pip setuptools
$ sudo pip3.5 install bigchaindb

Any advice would be really helpful

Thanks

Start with Error_Trace_log.txt and compare the reported failure with the installation commands in the issue and the linked BigchainDB quickstart. Check whether the problem is specific to pip3.5, Ubuntu 16.04, VirtualBox, or the package download step. Done means documenting a reproducible cause and a verified installation path, or confirming that the issue is environmental.
