After update to 2.868: no wifi

Volumio Version: 2.868
Hardware: RPi 3B+
DAC: Allo DigiOne

Steps to Reproduce

  1. Enable beta builds
  2. Upgrade to 2.868

After upgrading to 2.868, Volumio doesn’t connect to my previously configured AP anymore. Also, no APs are listed in the network settings.

This can be fixed by adding a country to wpa_supplicant.config
