• Create an org
• Create a dummy firmware image in the new org
• Launch a mass upgrade operation for the firmware image (alternatively use the django shell to create it) and org created in the previous steps
• Now try to delete the org

Expected outcome:

• The confirmation page is shown
• Once the operation is confirmed, the delete is carried out successfully

Actual outcome:

Cannot delete organization
Deleting the selected organization would result in deleting related objects, but your account doesn't have permission to delete the following types of objects:

• Mass upgrade operation

We seem to inherit this problem from openwsip-utils:

https://github.com/openwisp/openwisp-utils/blob/dd1b06f28bc6466645eccf4a7fb4af1086b84a62/openwisp_utils/admin.py#L36C5-L37C21

It's highly likely we'll have the same problem elsewhere, therefore finding a generic solution in openwisp-utils would be great.
