sudo apt update fails on balenaFin recommended Raspbian image

When I try to ‘sudo apt update’ it fails with 'E: The repository ‘https://dl.bintray.com/balenaos/raspbian stretch Release’ odes no longer have a Release file. This is on the balenaFin v1.1 and with the recommended Raspbian image.

I need this to update so I get upgrade from Python 3.5.3 to 3.8.

Not sure what to do, does anyone know how I can fix this?

Hello @evanfitzgerald ,

Sorry for the late response. We’ve been working on this for the past few weeks and we have a few updates:

  • In order to release a newer version of Raspbian, we needed to upgrade the kernel to 5.10. The wireless module gave us a few headaches, so it took more time than we originally anticipated.
  • We have a build that’s being tested and we plan to release it in the next days.

Do you have a specific Raspbian version that would allow you to update to python 3.8?

Cheers,
