sudo apt install git python3-pip build-essential wget python3-dev python3-venv python3-wheel libxslt-dev libzip-dev libldap2-dev libsasl2-dev python3-setuptools node-less

Issue is with Python 3.8 ,Need to downgrade python to version 3.6 or above, as previous versions are not compatible with Odoo.12

If you are installing in virtualenv, you can create your virtualenv with Python version below 3.8.4. The issue is with version 3.8.4 and above.

For an OS with Python 3.8.5 like Ubuntu, you can update your install with the latest nightly build for Odoo 12 which works with newer versions of Python 3.8 to fix your Odoo installation. No need for any database migrations.

The patch is only for v13 and not for the v12.

Yeah, but the changes are very similar on 12 if you are directly editing.

Hello Abdullah
You are getting issue because of python version 3.8,so you need to downgrade your python version to 3.5 or 3.6 and set it to default version.

This artical will help you to downgrade and set default to python version 3.5.

Use conda environment with odoo, You can install specific python version and needed dependencies in a isolated environment.

Thanks

Thanks for replying sir can u please tell how to do that because while installation we do not specify python version and when we install python3-pip it automatically fetches the latest version

@Abdullah

I hope this article helps you

https://hackersandslackers.com/multiple-versions-python-ubuntu/

And then I suggest you to use virtualenv with the specific python's version

like : virtualenv -p /usr/bin/python3.6 venv
