Do help me out raising issues, they’re most likely string to bytes, unicode, etc. etc. syntax. Will dispatch fixes immediately!
Will do …migrating now …

Are we not kill UBUNTU 14.04-32bit if we care to install Python 3.6?
"Python 3 is already installed on all currently supported Ubuntu releases. On Ubuntu 14.04, you have Python 3.4. You should normally avoid installing your own Python versions, because the system heavily depends on those which are preinstalled. "
It is not the time to upgrade VM virtual image to UBUNTU 16.04 64bit from UBUNTU 14.04 32bit?
Github issue:
Hi,
I’m new to EXPNext but I do know python and I would like to help out by testing new installs on Debian. Here are the steps that I used 
apt update
apt upgrade
locale-gen en_US.UTF-8
apt install -y python3 python3-pip
echo "frappe ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
wget https://raw.githubusercontent.com/frappe/bench/master/playbooks/install.py
python3 install.py --production --user frappe --mysql-root-password ***** --admin-password ****
Please let me know if this is the ideal way to do a fresh install
TIA!

I tried it with PyPy.
It worked seamlessly (almost). I could see some performance improvements too!
Known issues:
- PyPDF2 merging (using PdfFileWriter class) doesn’t work.

Can you write it up? Maybe a page on the wiki?
And what was the use case for PyPy or was this just an experiment?
Its simple really.
# Add PyPy repository
sudo add-apt-repository ppa:pypy/ppa
sudo apt-get update
# Install relevant packages
sudo apt-get install pypy pypy-dev
# Install dependencies
sudo apt-get install libxml2-dev libxslt1-dev
sudo pip install lxml
# Migrate environment! (execute from your bench instance)
bench migrate-env pypy
This was an experiment, primarily to check out the perfromance of PyPy compared to Python. It advertises 7.6 times faster performance.
I did not test benchmarks, but there was some visible improvement in comparison to Python.
However, it is not as stable as Python. If your instance requires PyPDF2’s merging features, you must use Python. Another alternative might be to make use of both implementations to get a proper balance of performance and stability.

Hello;
I succeeded with bench migrate-env python3 but I am facing problem when I run bench update --reset as I am getting this error:
TypeError: the JSON object must be str, not ‘bytes’
I faced the problem of Command "python setup.py egg_info" failed with error code 1 but the solution was by modifying the setup.py file at the repository of the custom application.
(Reference: [Solved]Command "python setup.py egg_info" failed with error code 1).
And below is the details

@achillesrasquinha, is ERPNext with python 3 really not production ready or is it just the python 2 to python 3 migration which is not ready ?
I’m asking because I plan to setup a new “production” ERPNext instance and I would prefer to go directly to python 3 instead of going through the hassle of later migrating…
We’ve been using python3.7 with ERPNext for 4 months now on our production with thousands of transactions per day. Runs as smooth as butter.

Thanks for your suggestion, it works on production VM.
Now it works with python3

May be it is for development not for production (master). Is the reason you restart bench?
