Dear friends,

I have a beginners question. I had my 8266 running happily under Windows and the arduino IDE. Now I switched to Ubuntu Linux, and when I compile my sketch it works fine but it does not download to the board. I get the following message in a mixture of English and German

Arduino: 1.8.5 (Linux), Board: ‘Arduino Yn’

Der Sketch verwendet 3706 Bytes (12%) des Programmspeicherplatzes. Das Maximum sind 28672 Bytes.
Globale Variablen verwenden 151 Bytes (5%) des dynamischen Speichers, 2409 Bytes fr lokale Variablen verbleiben. Das Maximum sind 2560 Bytes.

Has anyone run into this problem, and found a solution?

Thanx so much
