This is with the exact same IPA file. I know you're asking the guy who was trying on Linux, but I want to also highlight that the same IPA file uploaded via the GUI of the MacOS Transporter app works, while passing that IPA into the command line interface for Transporter doesn't work.
I suspect the MacOS Transporter GUI is using a slightly different version of the ITMS Transporter binary than the CLI or Linux Transporter app are.
