Your help will be much appreciated !

I experience the same issue, but trying to upgrade from 1.0.3 to 5.0.1

It seems to be an issue with python versions: python - Cannot import 'collections.abc' when using windows subsystem for linux - Stack Overflow

EDIT: it’s actually a pip dependency… read below

Ok actually it seems it’s a pip dependency issue.

I just checked my requirements.txt and found this:
SQLAlchemy-Utils>=0.29.0

It’s the only one that doesn’t match an exact version, so it must be now installing a recent version that’s not backwards compatible with python 2.

Try changing that package to an exact version, like SQLAlchemy-Utils==0.32.21 . Note it’s gotta be the requirements file under the version you are installing (v4).

You might have to edit the script or run some things manually…
I think re-running the upgrade script might overwrite the requirements file even if you edit it first. See if it works, if not then maybe install exact version manually using pip install, and repeat. If it still fails, you’ll have to get creative. :sweat_smile:

EDIT: 0.29 is extremely old (2015) so try 0.32.21 which was released around the same time (end of 2017) as the other sql-alchemy packages in the requirements file.

I’ve checked the SQLAlchemy-Utils version installed on my instance :

$ pip show SQLAlchemy-Utils
Name: SQLAlchemy-Utils
Version: 0.36.8
Summary: Various utility functions for SQLAlchemy.
Home-page: https://github.com/kvesteri/sqlalchemy-utils
Author: Konsta Vesterinen, Ryan Leckey, Janne Vanhala, Vesa Uimonen
Author-email: konsta@fastmonkeys.com
License: BSD
Location: /usr/local/lib/python2.7/dist-packages
Requires: six, SQLAlchemy

EDIT : I’ve downgraded my SQLAlchemy-Utils to 0.32.21 and the upgrade script finished successfully :slight_smile:

indeed downgrading it to version 0.32.21 worked for me too.
Many thanks @androsj you are a true legend here !!!
