Hi, so these are likely two issues:
- Debian Buster not having that image, and thus will need to update the project (or downgrade to Stretch)
- Pi4 being 64-bit ARM device, might not have the same packages available, so switching to 32-bit raspberrypi3 image,
balenalib/raspberrypi3-node:10-stretch-build
and similar might unblock you.
For the Wifi, the Pi4 that we have at hand we could connect successfully all the time. Can you share what exact project are you deploying? Because https://github.com/balena-io/resin-electronjs does not have any wifi connect so it’s harder to check your particular use case.
But it definitely feels like both the electronjs project needs a refresh, and wifi-connect needs more looking into for 64-bit ARM (in case).
