Bug Report

Current behavior

$ arduino-cli board list
Error detecting boards: Error getting board list: [listing ports from discovery builtin:mdns-discovery: command failed: mdns lookup error: failed to bind to any unicast udp port]

board list commands returns an error when called with no active network connection, this happens because the mdns-discovery process searches for boards in the currently active local network.

Expected behavior

board list error doesn't return errors if mdns-discovery can't find an active network connection.

Environment

  • CLI version (output of arduino-cli version): arduino-cli Version: git-snapshot Commit: 12adc538 Date: 2022-01-03T08:54:26Z
  • OS and platform: Arch x64
