Unable to deploy to phone: 'Xperia XA2 WIFI - Dual SIM (ARM)' is not a known device

I’m not using Docker, I’m using Virtual box. The key name and location were just the default. I didn’t choose anything other than to create one ~/.ssh/qtc_id

Just give a different name for the new key: in the SSK Key Configuration dialog (the one which opens after clicking “Create New Key Pair”), click “Browse”, and write a different name there.
