Django is crashing and log is showing "ModuleNotFoundError: No module named 'encodings'" after Ubuntu Upgrades

Question

So I made a huge mistake.. We had a running Django app on an Ubuntu server on AWS I was in the process of updating the website, and after I pulled my latest ORIGIN, everything was ok, and the changes were applied.

Ubuntu asked me to update/upgrade 150+ packages + 2 important security ones.. I am mostly a front-end developer and this was very new to me, so I thought what's the worst that can happen?

I used the command do-release-upgrade as Ubuntu suggested, and I wish it did not..

After everything was done updating, the website crashed, and the error log is being filled up by this error:

//and it keeps repeating

I have been researching for literally 7 hours, and I have tried many solutions that other people suggested like creating a new virtual environment.

It's been suggested to try and reset PYTHONHOME and PYTHONPATH, but I have been trying, I am not experienced with Python nor Django at all.

Server version: Apache/2.4.29 (Ubuntu)

Distributor ID: Ubuntu

Description: Ubuntu 18.04.2 LTS

Release: 18.04

Codename: bionic

Python Current version: 3.5.2

Stupid me did not take a snapshot of the server as I thought I wouldn't need it...

I could use all the help I can get. What can you suggest for me?

no module found is a common python error. there are many possibilities. In you case, some of old package is no longer compatible. update, upgrade sudo pip3 install . there are a lot of solution online. — Dr Yuan Shenghai, Jun 07 '19 at 17:49
Can you please tell me how to start? I am really desperate here — PythonBeg, Jun 07 '19 at 22:32

1st turn off all update to prevent further mistake.

then. remove and reinstall python 3. https://linuxize.com/post/how-to-install-pip-on-ubuntu-18.04/ follow this link to get python 3 up. High chance a lot of python 3 modules is not running.

After that follow this ImportError: No module named 'encodings'

m -rf venv
virtualenv -p /usr/bin/python3 venv/
source venv/bin/activate
pip install -r requirements.txt

At last, reinstall django, follow this https://www.digitalocean.com/community/tutorials/how-to-install-the-django-web-framework-on-ubuntu-18-04 to get django up

set up PYTHONPATH accordingly. this is very important use google if necessary

If some other package is not running, go find its GitHub root and use the script provide in github readme to install it.

Re run all your things again.
