Hi, how to upgrade module from command line in V13 CE all in one set up?
This still works the same as in old versions, by using the -u command. For example, if you have an app named "sales_management" and an app named "project_management" you would do:
./odoo-bin -u sales_management,project_management -c /etc/odoo-server.conf
Alternatively you can stop and start your Odoo instance, update the apps list from Apps > Update apps" and by then clicking on "Update" in the app itself.
You can find more information about the command line options in the official documentation
