Thought it sholuld be fixed after all the time...
Not really helpful that installation just fails without any hint!

The hint is "!MESSAGE Failed to download "http:downloads.arduino.cc/cores/ArduinoCore-mbed-nonexistant.tar.bz2"."
I say: "Not really helpful of arduino to publish platforms that that need to install nonexistant files"
