I’ve run into this lovely bug with the make package-dev build: https://bugs.launchpad.net/maas/+bug/1702567
It means that when I go to do a Commission operation, I get the error:
Error:name 'maas_api_helper_py' is not defined at line 17 column 3 in file /usr/lib/python3/dist-packages/metadataserver/user_data/templates/script_runner.template
Is there definitely no one that can advise on creating a development environment that works?
