The new version of Octoprint recommends Python 3.6, but after the re-image of the SD Card, I encountered an issue with WiFi (again...)

Cause: It looks like even though the card was configured correctly, it was not starting up on it's own Resolution: 1) Modify the  /boot/octopi-wpa-supplicant.txt network={   ssid="SecretNetwork"   psk="SecretPassword" } country=CA # Canada For some reason, the network wasn't coming online by itself even with the correct PSK, however, because of a lack of logging (or, me finding that logg...
