Custom edx-platform git repository on your Open edX deploy (devstack) If, despite the configuration of the /edx/app/edx_ansible/server-vars.yml file, the update script continues to fetch data from the edX repository (rather than the one you configured), then you can manually push the new origin into the repo:
Delete demo course from Open edX Use below command: cd /edx/app/edxapp/edx-platform/ sudo -u www-data /edx/bin/python.edxapp ./manage.py cms --settings aws delete_course course-v1:edX+DemoX+Demo_Course commit
Manually resync Open edX database after an update If, like me, right after Open edX platform update you incur in some error, the cause could be the mysql database not synced with the new models.
Open edX, modify lms.env.json in devstack If, while working with devstack distribution of Open edX you have difficulties with lms.env.json and lms.auth.json content (e.g. your configurations are ignored), have a look at:
Open edX, vagrant dirty shutdown and MongoDB You always have to keep in mind that command vagrant up turns on a virtual machine. When you turn off your workstation, remember to turn it off gracefully (with command vagrant halt or via SSH console).
