odoo160: Fixes to use py3.10

runbot.odoo.com is using python3.10 check the following branch 16.0 builds:

• https://runbot.odoo.com/runbot/bundle/16-0-128639
  • Checking the following install pip log:
    • http://runbot108.odoo.com/runbot/static/build/19641963-16-0/logs/install_all_split.txt

It shows the following output:

• Requirement already satisfied: Babel==2.9.1 in /usr/local/lib/python3.10/dist-packages (from -r odoo/requirements.txt (line 1)) (2.9.1)

(Notice the python version used 3.10)

In fact, We were using py3.10 but it needed a revert, check the following thread:

• https://git.vauxoo.com/mexico/l10n-mx-edi-hr-expense/-/merge_requests/1#note_435454
  • The MR related to reverting:
    • !417 (merged)

I have created this issue to follow up on the problem/fixes and be aware when it is fixed in order to change the current beta branches using odoo 16.0 and project-template to change the python version used

We don't have any projects using 16.0 right now

So it is not a priority or urgent
