In order to upgrade the python version it is necessary to remove the current version from the server.
You can find the installed python version in the following path cd /home/odoo/pyenv/versions/.
Remove all the versions including odoo.
The odoo_release should also be removed since it depends on python’s version.
It is under the path /opt/odoo_releases.
Here the example commands, using -rf in order to force delete all the content of the folders:
rm -rf 3.7.13/ odoo/
rm -rf odoo_12.0.12.0_2022-04-04.tar.gz
This procedure should be made manually until we integrate it to odoo-role.
