@Marostegui reported transfer.py fails after using the debian package for deployment:
transfer.py can be called and can show help normally, but it always says directory not exists (even if it does).
Funnily, HEAD works ok when locally cloned and used. My guess it is some path issue when building/installing the package + bad error reporting. E.g. cumin fails to be called but reports as "directory not found"? Or could be an infrastructure issue.
Testing environment would be key to debug the issue.
